Selene’s royal selection day ends in disgrace when Cassian abandons her for her sister, branding her a worthless low-grade Onyx. Forced out and looked down on, she makes a fateful purchase from the underground market: a mute, enigmatic slave. Hidden beneath her rejection is the extinct blood of the Obsidian dragon, and hidden beneath his silence is the identity of the lost Ancient Dragon Prince. Then the balance shifts again, as both sisters end up with dragon eggs—one worshiped, the other mocked.
