As a professional thief, Callum has seen and heard it all- from the most benign of actions to the foulest of words, very little about the world surprises him anymore. However, what he overhears in the hallowed halls of the city’s cathedral shakes him to his core: holy men evoking unholy things, devising a plan to open the barrier between their world and a cosmic, demonic force. With the help of a pastry chef, and the last living member of a mysterious family line, Callum seeks to put an end to this diabolical plot. To do so, he’ll need to reunite with his old crew. But dangerous lies and a history of jobs gone wrong have soured their relationship, forcing a group of haggard misfits to work with the one man they hoped to never see again.
