Between one blink and the next, Sandra Walsh's world turns from mission to horror.

As a lethal sniper for SweetBriar Group, a covert agency with assassins for hire, Sandra Walsh has no room for error. Accidentally killing a young girl she's supposed to save, Sandra knows she has to retire. Unable to leave without consequences, she fakes her death and establishes a new identity in North Carolina. Her vows to never pull another trigger or have contact with her former life again have been no problem...until her past threatens Casper Grady.

Grady has retired from the Marines. He's gone from protecting the nation to establishing a safe haven for local children and families. With his pained past, he has a debt to settle and his entertainment center is where he can find redemption. When Sandra Walsh applies for a position, his instincts say she's not what she seems. Drawn to the mysterious woman, he can't deny her qualifications and hires her for the position. As time goes by he doesn't regret the decision, then her past brings trouble through his front doors. Determined to help Sandra, he refuses to back down even when her secrets become dark and dangerous.

The danger escalates and their attraction intensifies. Will their newfound love survive when they're forced to choose between each other and the people they've sworn to protect? They have to stay alive long enough to find out...
