They're on an emotional collision course that can only end in happily ever after, or utter devastation . . .

Iris: I see the world through statistics. Logic and routine. That's what keeps me sane.
Killian Doyle is my polar opposite. His merciless, passionate nature terrifies me. He kidnapped me to force his brother, my friend, out of hiding and back into the mafia. He says he'll let me go when he doesn't need me anymore.
I understand what he wants. The only real question is what I want from him. Because right now, I'm confused enough to think I want him to keep me forever . . .
Killian: She was collateral. My brother betrayed our family, and I intended to hold her captive until he did my bidding. I never imagined I'd want her like I do. I know I should keep my word and let her go when the time comes. But I can't.
I'm a collector of rarities and Iris is the rarest one of all. Because she's threatening to capture something I swore I'd never let anyone touch. My heart . . .
