When the Rebel Queen, a key figure in a resistance movement, is captured and brought to the prison gravely ill, Kiva is ordered to keep her alive long enough to face the Trial by Ordeal, a deadly series of tests that the queen is unlikely to survive. To protect the queen and honor a message from her family, Kiva volunteers to take the queen’s place in the trials. As she navigates the life-threatening challenges, Kiva must also unravel a deeper conspiracy within the prison while grappling with her own identity and loyalties.
