Myla, Seth, and Fings find themselves under siege in Deephaven, a city ravaged by the plague, and stalked by demons. Myla has returned with Orien to her native Deepwater to face her past. Learning she's in trouble, Fingers and Seth head off on a rescue mission. Myla doesn't need rescuing, thanks, but now that they're
in Deepwater, Seth delves into the secrets of a dead warlock and Fingers digs into the truth of his missing brother.
But as the trio converge towards a conspiracy against the throne, Deepwater is attacked by an incomprehensible enemy. As demons, madness and the walking dead stalk the plague-ravaged city, Myla discovers that saving her friends and family is more important than a glorious death, and Seth embraces the darkness within.
