The Survivor (Aces Book 3)

Ten years ago, against the advice of the most influential people in the world—her family—Amanda Hearst walked away from her security detail. She wouldn’t allow another person to risk their lives to save hers.
Hagan Carter wants the truth about the mystery woman who works with Titan Group. Her lethal moves and skilled evasion fuel a volatile attraction.
Their past should stay buried, and their future is impossible unless the couple risks their lives to understand why they can’t be together.
