Learning that she has Demon Rider blood in her, Kyra begins to feel like a monster. Her identity must be secret, or else she will be hunted. The only people who know besides her are Tristam, whose own secrets make him untrustworthy, and the imprisoned assassin James, who may reveal Kyra's secret to save himself. Demon Rider attacks continue on the Palace, and Kyra determines to use her newfound heritage to protect the city she loves--if only she is not betrayed first.

Sequel to: Midnight thief.
