From TikTok sensation Sierra Simone comes the first in the Lyonesse series, a spin-off of her bestselling New Camelot books. Tristan Thomas is lost. After leaving the army, the young former soldier is in limbo. Until, that is, he's hired by Mark Trevena, the owner of Lyonesse-DC's ultra-secret club-to be Mark's new bodyguard. He's drawn into Mark's dark, seductive world of power and desire, and slowly drawn to Mark himself, even though Mark is everything Tristan knows he shouldn't want: cruel and wicked and shamelessly amoral. But protecting Mark isn't Tristan's only duty: soon, Mark asks him to guard his soon-to-be bride as she travels home from Ireland on Mark's yacht.
