Centuries after a catastrophic world war nearly decimated the human population, a city arose from the ashes, ruled by an elusive and technologically advanced group called the Illum. At twenty-seven, Emeline lives in limbo, wasting away her days in a job sorting ancient human art for destruction and waiting to be selected as a Mate for a procreation contract. Where others look forward to being chosen, Emeline has never felt like she fit into a society where a person’s worth is determined by constantly monitored genes, health, and the ability to procreate. She’s struggled to keep her discomfort secret, but when she is finally chosen, her Mate is revealed to be a member of the Illum named Collin, a man who seems to be harboring secrets of his own. It is the first time an Illum has taken a Mate in decades, leaving Emeline—and others—baffled as to why she was chosen. Soon, she is swept into the dangerous game of Courting, filled with ballgowns, lavish dinners, and watchful eyes, where one wrong move can mean elimination. While parts of this elite lifestyle are unexpectedly appealing, the more embroiled she becomes, the more she sees its dark underbelly—and a rebellion rising in secret. Collin is confusing, both cold and protective, and worse, she finds herself drawn to the very last person she should be falling for: Hal, one of the resistance leaders. As she draws closer to both Collin and Hal, the Illum exercise their power in increasingly brutal ways, forcing Emeline to question everything—most of all whether she’ll have to give up her heart and even her life to stop them.
