Return to the magic of the Archipelago in the dazzling sequel to the runaway, #1 New York Times bestseller Impossible Creatures, hailed as “an instant classic” (Katherine Applegate, Newbery Medal Winner for The One and Only Ivan)!

Christopher Forrester woke to find a dragon chewing on his face—and his heart leapt for joy! He’d been dreaming of going back to the Archipelago, the secret cluster of islands where all the creatures of myth still live, and here was his summons.

But there is a poison spreading in the Archipelago. Rooting it out will involve a daring rescue mission on the back of a sphinx, a stealthy entrance to a dragon’s lair, and a death-defying plan to save a prisoner held in the heart of a castle. At the center of this storm is Anya: a small girl with a flock of birds at her side, a new-hatched chick in her pocket, and a ravenous hunger for justice.

Katherine Rundell’s second thrilling installment in the Impossible Creatures series involves castles, dragons, and revenge—the things of which great stories are made. The splendors within are brought to life with more than fifty illustrations, including a map and a bestiary of magical creatures.

As The Poisoned King opens, a teen-aged boy named Christopher is woken by a dragon chewing on his nose. Which is less dangerous than it sounds — this is a Jaculus dragon, a creature the size of a sparrow, but with an outsized sense of its own importance. Jacques — the dragon — has come with a summons: Christopher is required to come with him to the Archipelago immediately. Someone is poisoning the great dragons, and there’s no time to lose.

What is the Archipelago? It’s a magical world comprising many large and small islands, inhabited by an astonishing variety of humans and creatures, hidden from our own world and accessible only through certain connecting locations known as waybetweens. Waybetweens are protected and kept safe by Guardians, of which Christopher’s grandfather is one — as Christopher learned the previous summer while visiting him at his remote home in Scotland, which led to Christopher’s grand, dramatic adventures in Impossible Creatures.

Christopher is a good, brave person who would never ignore a call for help, so he returns to the Archipelago to discover that things are even worse than he feared. Upon arrival, he’s met by a sphinx, who instructs him that he has a detour to make before proceeding to the dragons: A princess named Anya is in desperate need of rescue, and his mission and her plight are bound together.

And so we meet Anya Argen, granddaughter of the king of the island of Dousha. Anya’s father has raised her far from the castle, free to explore the forest they both love and spend time with the creatures who live there. When the King insists that she learn to behave like a proper princess, they’re forced to return to the castle, much to Anya’s dismay. As the story opens, the King is murdered, and her father — heir to the throne — is framed for the crime, leaving the way clear for his younger brother to act as Regent until Anya comes of age to rule herself. But her uncle Claude is not a patient man, and Anya finds her own life threatened.

As Christopher and Anya’s journeys connect, they join forces to unravel the mystery of what’s happened to the dragons while also laying plans to keep Anya alive and rescue her father, now imprisoned and sentenced to death for the murder of the King. Their quest takes them to new and old friends, and brings them into contact with even more fascinating magical creatures, while also giving them time to develop trust, friendship, and loyalty to one another.

The Poisoned King is a terrific second book in this captivating middle grade series. It has the surprises and delights of encountering magical worlds and beings, journeying through lands with rules and customs so different from our own, and seeing two young humans struggle to fix situations that have gone very badly.

Christopher is as lovely as ever, and Anya is a compelling addition to this fictional world. She’s complex and spiky; her desperate need to save her father is paired with a burning thirst for vengeance, and we see her grapple with the idea of revenge and what its impact might be on the type of person she is and wants to be.

The Poisoned King isn’t quite as glorious as Impossible Creatures — but that’s to be expected in the 2nd book of a series. Impossible Creatures introduced us to a new magical world and its wonders; The Poisoned King tells another story in that world, but lacks just a bit of the awe that comes with a world-building introduction. That said, The Poisoned King is very good, and is a worthy successor to such a stellar first book.

As with Impossible Creatures, I listened to the audiobook, narrated by actor Samuel West (currently starring in All Creatures Great and Small as Siegfried Farnon). He is an amazing voice actor, with delightful voices for Christopher, Anya, and all the various creatures, from tiny dragon Jacques to a deadly manticore and more. I did have a bit of trouble understanding one or two non-human characters due to the pitch of their voices, but that was only for a fraction of the audiobook experience, and didn’t detract from the overall enjoyment at all.

Repeating my reading note from Impossible Creatures: While I loved the audiobook experience, I strongly encourage anyone going that route to also follow along with a print edition. The book is filled with beautiful black and white illustrations by artist Ashley Mackenzie that add so much to the story. A bestiary at the end of the book gives more in-depth explanations of the various creatures in the book, from Batrachomyomachian Mouse to Winged Unicorn, accompanied by illustrations for each. The visual delights of this book should not be missed!

I loved returning to the world of Impossible Creatures, and highly recommend The Poisoned King (but do start with the first book!). A third book, The Neverfear, is scheduled for publication in fall 2026, and I absolutely plan to read it.

First Lines Friday is a weekly feature for book lovers created by Wandering Words. What if instead of judging a book by its cover, its author or its prestige, we judged it by its opening lines?

  • Pick a book off your shelf (it could be your current read or on your TBR) and open to the first page.
  • Copy the first few lines, but don’t give anything else about the book away just yet – you need to hook the reader first.
  • Finally… reveal the book!

This week’s lines are from a middle grade fantasy series:

The day Christopher saved a drowning baby griffin from a hidden lake would change his life forever. It’s the day he learned about the Archipelago, a cluster of unmapped islands where magical creatures of every kind have thrived for thousands of years—until now. And it’s the day he met Mal, a girl on the run who desperately needs his help.

Mal and Christopher embark on a wild adventure, racing from island to island, searching for someone who can explain why the magic is fading and why magical creatures are suddenly dying. They consult sphinxes, battle kraken, and negotiate with dragons. But the closer they get to the dark truth of what’s happening, the clearer it becomes: no one else can fix this. If the Archipelago is to be saved, Mal and Christopher will have to do it themselves.

Impossible Creatures generated a ton of buzz when it was released last year… and now that I’ve read it, I can happily confirm that all the praise is justified: This middle grade fantasy adventure is outstanding.

Christopher and Mal are two young heroes from two different worlds. Christopher lives in the world we know, a perfectly ordinary boy (other than his strange ability to attract animals wherever he goes). His life changes dramatically when he goes to spend a school holiday with his grandfather in Scotland. There, he discovers an opening to a secret, magical world, of which his grandfather is the guardian — a role Christopher is meant to inherit someday when he’s older.

Mal is a spunky, adventurous girl with a coat that gives her the gift of flight, outsized bravery, and an insatiable curiosity. When a stranger attacks her for seemingly no reason, she’s set on a path that leads her to Christopher. Christopher is immediately captivated by the magical world she represents, and pledges to help keep her safe, escape the bad buys, and figure out why Mal’s world (the Archipelago) seems to be losing the magic that infuses it.

As Christopher and Mal’s quest begins, they’re joined by her pet griffin, the last of its kind, as well as by a hardened sailor who’s more than what he seems and a scholar who also realizes the threat to their world. Together, they set out to save the magic and to understand Mal’s role and why dark forces seem to be aligned against her.

I’ll pause the story summary here to say that this book is glorious! The characters are wonderful — especially Christopher and Mal, who are everything we’d want in young heroes, but also the cast of humans and other creatures whom they encounter. Some are allies, some are obstacles, some are enemies, but all are created with careful detail and splendid heapings of imagination.

The quest itself follows what may feel like familiar beats, as the core group journeys from destination to destination within the Archipelago, solving riddles, finding missing objects, and carrying out difficult tasks along the route to confronting the ultimate big bad — yet the terrific writing makes it all feel fresh and fun. The quest is deliciously exciting and action-packed, but the action is never at the expense of character development. Mal and Christopher both get plenty of soul-searching and introspection along the way, as well as the opportunity to establish the deepest of friendships and to discover truths about themselves and their worlds.

I listened to the audiobook, narrated by actor Samuel West (currently starring in All Creatures Great and Small as Siegfried Farnon). His voice is wonderfully suited to this tale; he fully embodies a large cast of characters, and is especially delightful as Mal, Christopher, and their protector Nighthand. I occasionally had trouble making out pieces of dialogue for certain non-human characters due to the accent and pitch of the voices used, but that was only for a fraction of the audiobook experience, and didn’t detract from the overall enjoyment at all.

A reading note: While I loved the audiobook experience, I strongly encourage anyone going that route to also follow along with a print edition. The book is filled with beautiful black and white illustrations by artist Ashley Mackenzie that add so much to the story — see below for a few examples!

Impossible Creatures is a terrific, hopeful, emotional book, and I loved every moment. A sequel, The Poisoned King, will be published later in 2025. There’s no cover yet, but I’ll be keeping an eye out for it, and I absolutely plan to read the book as soon as it’s available.

I had the pleasure of reading an earlier book by Katherine Rundell — Rooftoppers — last year, and loved it as well. This is an author to watch! I look forward to exploring more of her books, and meanwhile, will be counting the days until The Poisoned King is released.

Embrace possibility in this luminous novel about a girl in search of her past who discovers a secret rooftop world in Paris.

Everyone thinks that Sophie is an orphan. True, there were no other recorded female survivors from the shipwreck that left baby Sophie floating in the English Channel in a cello case, but Sophie remembers seeing her mother wave for help. Her guardian tells her it is almost impossible that her mother is still alive—but “almost impossible” means “still possible.” And you should never ignore a possible.

So when the Welfare Agency writes to her guardian, threatening to send Sophie to an orphanage, she takes matters into her own hands and flees to Paris to look for her mother, starting with the only clue she has— the address of the cello maker.

Evading the French authorities, she meets Matteo and his network of rooftoppers—urchins who live in the hidden spaces above the city. Together they scour the city in a search for Sophie’s mother—but can they find her before Sophie is caught and sent back to London? Or, more importantly, before she loses hope?

Phillip Pullman, author of the His Dark Materials series, calls Rooftoppers “the work of a writer with an utterly distinctive voice and a wild imagination.”

In this charming story about love, friendship, and believing in possibilities, an orphaned child sets off on an adventure across the rooftops of Paris in search of her long-lost mother.

Never ignore a possible.

Sophie was only one year only — or thereabouts — when she survived a shipwreck, and was found floating in a cello case by a kind man who decided on the spot to give her a home and a family. Charles Maxim raises Sophie with generosity and wisdom, encouraging her wild imagination and bravery, and teaching her to embrace whatever life has to offer, even against the odds.

Charles and Sophie’s life together is threatened by the official government agency which monitors guardianships. Aghast at Sophie’s inappropriate upbringing — including writing poetry on walls, wearing trousers, and learning from life rather than school — they inform Charles that Sophie will need to go to an orphanage.

Meanwhile, Sophie has yearned all her life for the mother she can barely remember — a woman who played the cello, and was presumably lost at sea. Sophie is convinced that her mother is alive — it may not be probable, but it’s at least a little bit possible — and when the authorities seem about to take 12-year-old Sophie away from Charles, the pair hatch a daring plan.

Following a very slender lead, they escape London and make their way to Paris, where the search for Sophie’s mother seems to hit a dead end. Sophie won’t give up though, and soon makes the acquaintance of Matteo and other “rooftoppers”, orphans who make their homes on the roofs of the city. The rooftoppers are tough and cunning and creative, and help Sophie find her way across the roofs as they follow mysterious cello music and chase down further hints and clues.

Rooftoppers is a lovely, sweet book that’s never overly sentimental. Charles and Sophie have a wonderful relationship: He clearly loves Sophie, but never hesitates to support her dream of finding her mother, and meanwhile ensures that she broadens her mind and experiences life to the fullest extent possible.

The adventure is terrific, with some glorious rooftop action sequences. The solving of the mystery may not be terribly realistic, but it’s heart-warming and exciting none the less.

As an adult reader, I found the ending rather abrupt. The book has a beautiful final scene, and perhaps for the book’s target middle grade audience, that will be perfectly satisfying. For me, though, I couldn’t shut out the “and then what?” that immediately came to mind. I liked the ending, but was desperate for an epilogue to tell me where the characters went from there and how it all worked out.

Other than that, I truly enjoyed reading Rooftoppers. It’s a book that I meant to get to years ago, and I’m glad I finally picked it up. Highly recommended for middle grade readers who enjoy a bit of whimsy and adventure — as well as for adults who enjoy beautifully written middle grade fiction.
