Eli Monpress attempts the ultimate heist job in the dazzling sequel to The Spirit Thief. When Eli is forced to take a dull job as payment for Nico's magical new coat, he tries to make the most of it, choosing as his target the Duke of Gaol's famously 'thief proof' citadel. Sure, it's a trap, but if Eli has to do pro bono work, he might as well get something out of it, and robbing a treasury that's never been cracked is certainly a start.
