While on another perilous mission, agent Thorn uncovers valuable information about the leader of a criminal organization—and herself Nyrielle “Thorn” Tam is sent to investigate a criminal organization and assassin’s guild—the House of Tarkanan—from which she must gather information on their leader. The mysterious Son of Khyber may be hard to track down, but as Thorn infiltrates this gang of criminals with special powers, she finds that she may have more in common with them than she thought. When her orders and experience contradict each other, Thorn turns to the Son of Kyber for guidance—and discovers that she is uncertain about where her own loyalties lie. As she questions her past and her own training, Thorn may uncover more about herself than she ever thought possible.
