Now well into her apprenticeship with magician Emery Thane, 20-year-old Ceony Twill is continuing to discover the joy of paper magic. She adores bringing her spells to life in surprising ways, from learning the power of distortion to creating a beloved paper dog. And she secretly hopes that the romance she foresaw blossoming between her and the peculiar yet strikingly handsome Emery finally becomes real.

Throughout her studies, Ceony Twill has harbored a secret, one she's kept from even her mentor, Emery Thane. She's discovered how to practice forms of magic other than her own - an ability long thought impossible. While all seems set for Ceony to complete her apprenticeship and pass her upcoming final magician's exam, life quickly becomes complicated. To avoid favoritism, Emery sends her to another paper magician for testing, a Folder who despises Emery and cares even less for his apprentice.
