Wandering Magic. Magic, Love, and Mischief, #4

Catherine Fry's world trip was supposed to be more of a farewell tour. After giving up her immortality to her student Bridget St. James, Catherine decided it was time to see forgotten friends and her old haunts. But when one of her former lovers demands payment on an old debt, Catherine is magically bound to complete the terms of the bargain or face dire consequences. Titania, queen of the fae, wants to acquire a magic item that is in the hands of a collector who just so happens to be a friend Catherine once left behind.
Calling upon her long unused skills as a master thief, she will have to pull off a heist in a place teeming with magic. Every heist needs a team, and every team needs a thief, a hacker, a warder, and a mastermind. Luckily-or unluckily-she knows just who to employ. Can Catherine pull off a magical heist while protecting her heart from past loves? Or will she betray not only everyone around her but also herself?
