Gage is a powerful warlock in Low Town, where elves, faeries, trolls, goblins, and vampires walk free alongside humanity. But there are two dangerous entities murdering parents and children, and Gage needs to stop them before anybody else gets hurt.

When Gage discovers a demon locked away, it offers him access to dark magic in exchange for its freedom—a dangerous opportunity, but one that could save his loved ones. Gage must choose between what is right and what is easy … except he’s running out of time.
