Emily Vance buried her past along with the girl she used to be. Now she's the flawless executive secretary to billionaire CEO Thane Rivers, a man known for his ruthless business instincts and impossible standards. Behind her calm smile is a carefully built life where every move is calculated, every emotion is controlled, and every secret remains buried. But when the past begins to claw its way back and her life is suddenly in danger, Emily is forced to make an impossible choice: place herself completely under the protection of the one man she swore she'd never depend on, or face the darkness she's spent years trying to escape. The closer she gets to Thane, the harder it becomes to tell where safety ends and obsession begins. Some secrets are worth dying for. Others are worth killing to protect.
