The ninth book in the fast-paced InCryptid urban fantasy series returns to the mishaps of the Price family, eccentric cryptozoologists who safeguard the world of magical creatures living in secret among humans.
Sarah Zellaby has always been in an interesting position. Adopted into the Price family at a young age, she’s never been able to escape the biological reality of her origins: she’s a cuckoo, a telepathic ambush predator closer akin to a parasitic wasp than a human being. Friend, cousin, mathematician; it’s never been enough to dispel the fear that one day, nature will win out over nurture, and everything will change.
Maybe that time has finally come.
After spending the last several years recuperating in Ohio with her adoptive parents, Sarah is ready to return to the world–and most importantly, to her cousin Artie, with whom she has been head-over-heels in love since childhood. But there are cuckoos everywhere, and when the question of her own survival is weighed against the survival of her family, Sarah’s choices all add up to one inescapable conclusion.
This is war. Cuckoo vs. Price, human vs. cryptid…and not all of them are going to walk away.
It makes me so happy to have a new InCryptid book in my hands, especially since I won this one in a Goodreads giveaway, which pretty much never happens for me!
In Imaginary Numbers, the ongoing InCryptid series turns to two new point-of-view characters, Sarah Zellaby and Artie Harrington. Sarah and Artie are both members of the sprawling Price-Healy clan, a group of cryptozoologists dedicated to protecting non-human species from the persecution of the deadly Covenant, and equally dedicated to protecting humans from the deadlier of cryptid species. To that end, the Prices are all highly skilled with weaponry of all sorts, learning to become excellent shots and to throw knives with precision from childhood.
Sarah is the first non-human main character in this series. She’s a cuckoo, the common term for Johrlacs, which are a human-appearing species that are more or less descended from telepathic wasps. Cuckoos are apex predators. They can take over anyone’s mind and make them do whatever they want, and the effects can be fatal. Sarah was adopted into the Price family as a child, and so was raised with a different set of influences than a typical cuckoo, making her more aware of her responsibility to respect others’ boundaries and giving her a deep, true love for her family. As well as a different and very strong love for her cousin Artie, which the two of them have been too shy and awkward to ever acknowledge.
In this book, Sarah’s return to the family compound after a lengthy recovery from injury brings the attention of unknown cuckoos, who want to use her for their own purposes, and don’t care who they have to kill to make it happen. The action is intense and fast-paced, with a plot that’s occasionally confusing but always fun.
The InCryptid books tend to be a little less dire than Seanan McGuire’s October Daye series, which regularly rips out my heart. This series is generally light-hearted, not that there aren’t perilous situations and heartbreaks here as well. Still, with a family that includes a sorcerer whose boyfriend is a human-sized monkey, a grandfather who’s patched together from dead bodies, and a time-traveling grandma who appears to be in her teens, things can’t get all that serious for too extended a time.
The author’s trademark quippiness and cleverness is on full display in Imaginary Numbers:
It wouldn’t stop the cuckoos on the lawn from pouring into the house if they got the signal — it would barely even slow them down — but every little bit helps when you’re going up against telepathic killers from another dimension.
… [T]hat made it better than standing around waiting for the invisible floor to drop out from under my feet and send me plummeting into the void. I am not a big fan of plummeting. If I had to commit to a position, I’dd probably have to say that I was anti-plummeting.
“She seems nice.”
“No, she doesn’t,” I said. “She seems like an unstable old lady who somehow keeps aging backward, and who carries grenades that are older than I am way too frequently for comfort’s sake.”
Normal people get meet-cutes. I get crime scene cleanup.
Imaginary Numbers ends with a sort-of cliffhanger — the main plot is resolved, but ends up dumping a few key characters into a brand-new situation in the last lines… and I’m dying to know what will happen! It sounds as though the next in the series, Calculated Risks, will pick up where this one leaves off. Too bad we have to wait a year for it!
As an added treat, Imaginary Numbers includes a bonus novella, Follow the Lady, which takes place chronologically between books 8 and 9. It’s fun, not earth-shattering, and a nice way to de-stress after the high-pitched excitement at the end of Imaginary Numbers.
This series is a delight, and I’ll echo my previous advice to start at the beginning. These books do not work as stand-alones, not if you want to have any hope of getting what’s going on and the complex, convoluted family trees. All of the InCryptid books are fast reads, so even though this is the 9th book in the series, it really won’t be too hard to catch up.
I love these books! Check ’em out.

I’m dying to start this series. Not sure I’ll ever catch up, but I’m going to try at some point😁
I think you’ll love it! It’s pretty light most of the time, and the characters are just so awesome! (And there are very special mice, who are the highlight of every single book…)
