When Amanda signs up for a beta feature of the Obsess AI boyfriend app--a secretive new match program that claims to pair users with real-life partners who match their fantasy settings--she thinks it's just another marketing gimmick.

Sure, the guy it gives her is hot. Brooding. Protective. Motorcycle included. But he won't take off his helmet. Won't tell her his name. And somehow, he knows things no one else should.

She should be freaked out. She should stop letting him make her feel things. But something about him feels...familiar. What Amanda doesn't realize is that the man behind the helmet isn't a stranger at all. It's her ex-husband. The one who walked away without a word. The one she's spent years trying--and failing--to forget.

Now he's back. And he's not asking for permission. He'll stalk her. Protect her. And when she begs him to take off the helmet and finally show her who he is? He'll remind her: She asked for this.

She thought she was falling for someone new. But the truth? She might be falling for the one man who already broke her heart...and this time, he's not letting go.
