Emily picks up a stone that looks like a cell phone but has unexpected magical powers. It's a Spellstone! Now that she has become an unwilling Stonemaster—one who wields the power of the Stone—she has to figure out Spellstone technology fast if she is to survive a hair-raising adventure among giant dogs, demons, clones, mean girls, and deeply wicked people who want the Stone. A witty tale of a quiet girl who discovers she's a hero when she needs to be. Stonemasters rule!

She has an all-powerful magic phone and a demon servant who also wants to eat her. What could possibly go wrong?

• A Reluctant Hero: Quiet Emily just wants to collect rocks and read books, not save the world. Too bad the world has other plans.
• An Unlikely Friendship: Meet Gorgo, a nearly immortal creature of evil intent who is magically bound to obey Emily’s every command... when he’s not plotting to eat her for dinner.
• Wickedly Weird Villains: From the vile Venomüch family to Kristy Meyer, the queen of mean girls, Emily has enemies coming at her from every dimension.
• A Magic Phone: Forget apps—the Spellstone uses ‘apths’ to cast spells, open portals, and occasionally cover your drama teacher in ten thousand angry sparrows.
