Radiant Sin

The sizzling fourth romance in Robert’s Dark Olympus series (after Wicked Beauty) rewards readers with another high-heat adaptation of Greek myth. Cassandra Gataki and her younger sister, Alexandra, have been treated as outcasts ever since their late parents attempted a coup against the Thirteen, the ruling council of the dystopian city of Olympus. Determined to flee Olympus, Cassandra reluctantly agrees to pose as the girlfriend of her employer (and longtime crush), Apollo, at a fraught weeklong house party at a political upstart’s country home, if, in exchange, he’ll help her to leave Olympus for good. Apollo, the Thirteen’s spymaster, has been lusting after his beautiful assistant ever since he hired her, but his honor has prevented him from acting on these urges. Their fake relationship soon becomes all too real, however, even as Apollo uses it as a cover to investigate a rumored revolution. As the danger ramps up, the pair must work together to untangle deadly political intrigue. Exactly as spicy as Robert’s regulars expect, this twisty romance will keep readers guessing from start to finish, and the irresistible leads are sure to become fan favorites. This addictive series is nowhere close to flaming out. Agent: Laura Bradford, Bradford Literary. (Feb.)
