A new holiday story set in the Scottish Highlands to warm booklovers’ hearts by Jenny Colgan, New York Times bestselling author of Midnight at the Christmas Bookshop.
Mirren Sutherland stumbled into a career as an antiquarian book hunter after finding a priceless antique book in her great aunt’s attic. Now, as Christmas approaches, she’s been hired by Jamie McKinnon, the surprisingly young and handsome laird of a Highland clan whose ancestral holdings include a vast crumbling castle. Family lore suggests that the McKinnon family’s collection includes a rare book so valuable that it could save the entire estate—if they only knew where it was. Jamie needs Mirren to help him track down this treasure, which he believes is hidden in his own home.
But on the train to the Highlands, Mirren runs into rival book hunter Theo Palliser, and instantly knows that it’s not a chance meeting. She’s all too familiar with Theo’s good looks and smooth talk, and his uncanny ability to appear whenever there’s a treasure that needs locating.
Almost as soon as Mirren and Theo arrive at the castle, a deep snow blankets the Highlands, cutting off the outside world. Stuck inside, the three of them plot their search as the wind whistles outside. Mirren knows that Jamie’s grandfather, the castle’s most recent laird, had been a book collector, a hoarder, and a great lover of treasure hunts. Now they must unpuzzle his clues, discovering the secrets of the house—forming and breaking alliances in a race against time.
A treat for booklovers and treasure hunters alike, The Secret Christmas Library serves up a delicious mystery with a hint of romance, and plenty of holiday spirit!
Jenny Colgan’s books can be counted on for sweet romance, lovely settings, clever people, and simple pleasures, and The Secret Christmas Library delivers all of these… although the stakes in this particular book are mainly on the low end of the scale.
Last year, the author published a fun novella, The Christmas Book Hunt, in which a young woman named Mirren ends up on a search to find a rare book that her great-aunt remembers from her childhood. Seeing the book again is her dying wish, so Mirren turns book detective, chasing leads and sorting through dusty old shelves to make her beloved aunt’s wishes come true.
Surprise! In The Secret Christmas Library, Mirren is back! The rare book that Mirren found is proudly displayed in the British Museum, along with a plaque giving Mirren credit for finding it. Mirren is not (as the blurb might imply) a professional book finder; she’s kept her less-than-exciting day job as a surveyor, but dreams of spending more time with the books she loves. When she bumps into a stranger while visiting “her” book at the museum, and admits that she’s the person on the plaque, it’s the start of an adventure she could not have anticipated.
The stranger is Jamie McKinnon, who has just inherited the family estate in the Scottish Highlands. Estate? It’s more like a castle… although it’s on the verge of falling apart, deeply in debt, after years of family neglect and mismanagement. But Jamie’s grandfather always implied that there was a secret treasure to be found there — a book worth more than anyone could imagine. Jamie is desperate to save the estate, and hires Mirren to come look for the book.
To Mirren’s surprise, he’s also hired Theo, her competitor/partner on her previous book hunt — someone she thought might be a romantic partner too, until he ghosted her after their last adventure. She’s not thrilled to be reunited with him, but is determined to put feelings aside to pursue this new quest.
The castle is indeed a disaster, and Jamie’s grandfather appears to have been a hoarder, at least when it comes to books. There are miles and miles of overflowing shelves throughout the corridors, and even the cupboards are stuffed with books. Their only clue is a poem the grandfather has left behind, full of cryptic clues and strange references. With only a few days until Christmas and a heavy snowstorm leaving the group stranded, they devote themselves to trying to decipher the clues and locate the book… assuming it even exists.
Meanwhile, as Mirren gets to know Jamie, she realizes that this handsome laird has an inner sweetness that she feels drawn to. And the more she comes to care for Jamie, the more important finding that book and saving Jamie’s home feels to her.
The Secret Christmas Library really takes a while to get going. There’s lots of loveliness — an old-timey train, scenes of exploring the castle, fancy dinners (with men in kilts!), a sweet nostalgic feel once the power cuts out and they dance by candlelight to an old Victrola. The book hunt is cute, but not particularly engaging… at least for this reader. Personally, I find I don’t have much patience for this sort of plot — finding hidden objects, discovering clues in old pictures, following a word puzzle to a particular location. (Maybe that explains why I have no interest in escape rooms either…)
In any case, these type of scenes make up a good portion of the book. It’s nice, but not terribly exciting. Things get a little more dramatic when the weather and some other elements combine to put the people — and the castle itself — in grave danger. A dramatic escape as well as the escalation of various personal connections and relationships make the last 25% or so much more engaging — finally, some stakes to truly care about!
The audiobook is narrated by Eilidh Beaton, narrator of many Jenny Colgan books. Her delivery is warm, with an engaging cadence, and she excels at the various characters’ accents and speaking styles. I found it easy to get into the story, and the narration never let my interest wander.
Overall, this is a fun, sweet book, but not quite as wonderful as some of the author’s other books. I’d still recommend this book for Jenny Colgan fans who’ve read all her books and gobble up her new releases as soon as they’re available (guilty!!). For those newer to her works, I do think this is a fine choice, but there are others I’d probably recommend more highly to get a true taste of how lovely her books can be.

Hi Lisa, I haven’t read any of Jenny Colgan’s books, but they are popular at the library and a few of my coworkers have recommended them to me. Thanks for the review – just in time for the holidays!
Definitely a sweet choice with the holidays around the corner! I’ve loved so many of Jenny Colgan’s books. I think the Mure series may be my favorite, but pretty much any give a good taste of the vibe of her books!
I loooove this cover! It looks so cozy and inviting and magical. I’m glad it was a good read, even if it wasn’t quite as good as some of the authors other ones!

Thank you! I agree about the cover 🙂 and I did like the book, just feel like there are others that I loved!
👍
The set up sounds like so much fun, but I would probably be frustrated too by the lack of excitement, lol.
It does pick up by the end 🙂 and I find that listening to this author’s audiobooks is the way to go for me — a very cozy experience!
