Edge of Temptation by Gennita Low

From New York Times best-selling author Cristin Harber and New York Times, USA Today best-selling author Gennita Low comes an exciting collaboration…

Walker, Titan’s newest recruit, has been sent to rescue Nadine Kincaid, DARPA’s scientist working on a special state-of-the-art exoskeleton for COS Command’s Super Soldier Spy Project. Instead, the tied-up Nadine turned out to be Nadia, Nadine’s twin sister, who has been protecting her sister all along. Now the two of them have to work together to keep the newest exoskeleton blueprints out of the enemy’s hands.
