Jessica Khoury wrote her first book at age 4, a fan fic sequel to Syd Hoff's Danny and the Dinosaur, which she scribbled on notebook paper, stapled together, and placed on the bookshelf of her preschool classroom. Since that day, she's dreamed of being an author. When not writing, Jess enjoys spending time with family, playing video games, and oil and watercolor painting. She is also a professional mapmaker, and spends far too much time scribbling tiny trees and mountains for fictional worlds. Jess currently lives in Greenville, South Carolina. She is the author of the Corpus trilogy, The Forbidden Wish, Last of Her Name, and The Mystwick School of Musicraft.
