Can two sneaky tweens solve the mystery of the girl in apartment thirty-six? 

Valory has developed an unfortunate reputation as a thief—primarily because she steals things—though she has resolved to change her ways. Rook is a total asparagus-eater (a.k.a. a good kid), but he likes to spy on his neighbors. Nobody’s perfect, right?

The twelve-year-olds form an unlikely alliance when they encounter suspicious behavior in an “empty” apartment across the alley from Rook’s house. While agoraphobia keeps home-schooled Rook trapped on his property, confident and street-smart Valory can roam the scene undetected. Their opposite personalities might, in fact, be key to their success.

But their amateur detective mission morphs into something more sinister when they realize the apartment next door could be connected to a recent kidnapping. When the sleuths realize they’re also being watched, the pressure is on to unmask the villain… before she snatches them, too.

More on Sneaks

“A fun whodunit that no young reader will be able to put down. You can’t help rooting for Valory, despite her imperfections, and the intriguing friendship between her and Rook sparkles with charm. A sweet—but deliciously engaging—must-read mystery.”

—Claire Swinarski, author of Edgar Award Nominee What Happened to Rachel Riley?

 

A double-dose of mystery and heart! I was hooked from the very first page of this clever Middle Grade debut. The dual narrative is masterfully handled. It’s rare to find a story where you feel so equally invested in both leads. Each character brings a unique “underdog energy” that makes you want to cheer (and sleuth) right alongside them. The mystery is tightly plotted, and the shenanigans are as fun as they are heartfelt. A perfect pick for young readers who love a good puzzle and characters with real depth. Highly recommended!
