Escape the Night — Desiree Holt

When Anya Kane escaped the darkness Virgil Branson was selling her into, she sought help from her boss, Gus D'Amato, a hot and hunky FBI agent. Six months later she is out of his office and in his bed, enjoying the most erotic sex imaginable and forging a bond with the man who makes every muscle in her body quiver. But things go dramatically wrong, and between bouts of thermonuclear sex that set them both on fire, Gus finds himself struggling to keep them both safe.
