Mo lives on Fox Street with her dad and little sister, the Wild Child. Their house is in the middle of the block—right where a heart would be, if the street were a person. Fox Street has everything: a piano player, a fix-it man, the city's best burrito makers, a woman who cuts Mo's hair just right, not to mention a certain boy who wants to teach her how to skateboard. There's even a mean, spooky old lady, if ringing doorbells and running away, or leaving dead mice in mailboxes, is your idea of fun. Summers are Mo's favorite time, because her best friend, Mercedes, comes to stay.
Most important, though, Fox Street is where all Mo's memories of her mother live. The idea of anything changing on Fox Street is unimaginable—until it isn't.
This is the story of one unforgettable summer—a summer of alarming letters, mysterious errands, and surprising revelations—and how a tuft of bright red fur gives Mo the courage she needs.
Mo Wren knew that eventually she, her dad, and her sister, Wild Child Dottie, would have to move from beloved Fox Street. She just never expected it to happen so soon.
At the Wrens’ new place, things are very different. The name of the street—East 213th—has absolutely zero magic. And there’s no Mrs. Petrone to cut her hair, no Pi Baggott to teach her how to skateboard, no Green Kingdom to explore. She’s having trouble fitting in at her new school and spending a lot of time using the corner bus shelter for her Thinking Spot. Worst of all, Mo discovers that the ramshackle restaurant Mr. Wren bought is cursed. Only Dottie, with her new friends and pet lizard, Handsome, is doing the dance of joy.
For the first time in her life, Mo feels lost and out of place. It’s going to take a boy who tells whoppers, a Laundromat with a mysterious owner, a freak blizzard, and some courage to help her find her way home for good.
