The Promise of Surrender (1001 Dark Nights Series Novella)

Mia Russo spent ten years working undercover, entrenched in the dregs of society before handing in her shield. Opening her own pawn shop is a piece of cake in comparison. All she needs is the bad attitude she developed on the streets and the shotgun under her counter to keep law and order. Until the day Zeke McBride walks into her shop. Zeke knows Mia has every right not to trust him. He was the one who chose the next op instead of her. And all he can hope is that somewhere under the snarl and cynicism is a woman who can forgive. Because whether she trusts him or not, they're going to have to work together to bring down the gang that's decided Mia is their next target.
