Elwyn is remarkably unremarkable, and she prefers it that way. Perhaps it is a talent owed to the training of the notorious syndicate that reared her, or it may be a gift from her invisible friend—a clever and capricious creature who, unlike most invisible friends, has only grown more real with time. Either way, Elwyn's unremarkability is about to fail her. Upon absconding to the tiny town of Amblewick in search of a quiet, uneventful life, she catches the attention of two feuding tricksters, each in the market for the perfect pawn. Through either fate or magical machinations, she soon finds herself in the company of a cutthroat assassin, a wayward prince, and a little girl with a chilling secret. Despite their differences, this ragtag group of ruffians just might manage to save multiple worlds...provided they don't kill each other first.
