With the future of civilization hanging in the balance, elite Time Enforcer Saron Bahl is sent back to the twenty-first century to protect the one woman whose survival will ignite a new Age of Enlightenment. But when the mission collides with secrets from Saron's past, the timeline—and her heart—begin to fracture. Avery Simpson, a pacifist and the reluctant leader of the Sapphites, is skeptical of the tall, imposing stranger who claims to be from the future. Yet despite her doubts—and her disapproval of Saron's ruthless methods—Avery can't deny the magnetic pull between them. As the relentless Traditionalists close in, survival may depend on more than strategy and strength, but the Sapphites prove far more formidable than anyone ever imagined. Caught between duty and desire, Saron and Avery must decide what they're willing to sacrifice—for the world, for their cause… and for each other.
