THE MOSSHEART’S PROMISE (Book 1, September 2023)
The mold takes all.
Twelve-year-old fairy Canary Mossheart knows this better than most. A few years ago, the mold took her papa, and even her famous, former-chosen-one Gran never found a cure. So when Ary’s beloved mama falls ill, Ary decides it’s taken enough. Armed with only a bucket and a prayer, she sneaks out to find a magical, underground lake whose healing waters are straight out of Gran’s adventures.
But when Ary gets there, the lake’s bone dry, and instead of healing waters, she finds a terrifying secret: Her entire world is actually trapped inside a giant terrarium—one they were meant to leave centuries ago. Worse, Gran knew and hid the truth, dooming Ary and her generation to a dying, rotting world.
Now, allied with only her doomsday-obsessed frenemy, a timid pill bug, and a particularly grumpy newt, Ary has one week to unravel the clues and find a way out of the terrarium—or they’ll be trapped for good.
THE GHOSTWING’S LIE (Book 2, October 2024)
Rebecca Mix is the New York Times bestselling author of stories about weird magic & hope. Her debut novel, The Ones We Burn, was an instant New York Times & Indiebound bestseller. Her other books include Neopets: The Omelette Faerie, the first of two official graphics novel developed in partnership with the game, slated for summer 2024.

Viktor Valentine can’t think of a better way to end his summer vacation than playing All the Vampires Everywhere, his favorite video game, with his best friend, Damon. Yet his parents, who make cringey jokes and call him dorky nicknames, seem set on ruining his plans. Viktor knows he can’t really compete with Damon’s “cool” friends—so their epic video game playing is the best Viktor can do to come close to being cool in Damon’s eyes.
Ella Moore was the most popular girl in school…and also the most hated. When she’s murdered at her own party, there are too many suspects to count. And too many people who think she deserved it.
Hayley always has a crush. The problem is, her crushes never like her back. After her latest unrequited love—a girl from her basketball team—gets a boyfriend, she decides she’s done falling for girls who are unavailable. Her best friend, Talia, wants romance too, but rarely gets crushes on anyone, and she’s tired of watching Hayley get her heart stomped on over and over. So the two girls make a pact: they’ll help each other find summer love by putting themselves in situations that always lead to romance in movies.
