A Librarian's work is never done, and Irene is summoned to the Library. The world where she grew up is in danger of veering deep into chaos, and she needs to obtain a particular book to stop this from happening. Her only choice is to contact a mysterious Fae information-broker and trader of rare objects: Mr. Nemo. Irene and Kai make their way to Mr. Nemo's remote Caribbean island and are invited to dinner, which includes unlikely company. Mr. Nemo has an offer for everyone there: he wants them to steal a specific painting from a specific world. But to get their reward, they will have to form a team, including a dragon techie, a Fae thief, a gambler, a driver, and the muscle. Their goal? The Kunsthistorisches Museum in Vienna, in an early twenty-first-century world, where their toughest challenge might be each other.
