Lindsey Aeon has a secret—and it's not just her undercover identity. Twenty years ago, a hike in the Florida wilderness changed her life forever. After falling into a mysterious pool of cool, shimmering water, Lindsey emerged... different. She hasn’t aged a day since, and her body now boasts rapid healing, enhanced strength, speed, and agility. These extraordinary abilities make her an exceptional FBI agent, but they also make her life anything but ordinary. Now, Lindsey’s latest assignment takes her to Philadelphia, where she must go deep undercover to infiltrate a powerful mob family. Her mission: befriend the mob boss’s sheltered daughter and gather intel to bring the organization down. But while her superhuman skills keep her alive in dangerous situations, they’re no help in navigating the murky waters of human connection. Lindsey wasn’t expecting to form a genuine bond with the mobster’s daughter—or to be drawn to his deadly and seductive playboy son. As the stakes rise and loyalties blur, Lindsey must tread carefully to protect her mission, her heart, and the secret that could change everything. Some secrets are dangerous. Lindsey’s could be deadly.
