Disguised as a man to survive as a human slave, Rowan unexpectedly awakens a dormant Spirit Bloodline, saving Lion King Kairos from a Beast-Curse consuming him from within. Caught in a relentless push-and-pull of desire and defiance, the two fall in love across the boundary of species. Together they shatter the Wolf Clan's conspiracy, and Rowan rises from slave to Lion Queen, commanding the submission of all beasts.
