Say You’re Sorry by Jacey Ward

She. Killed. My. Brother.
Nothing can fix that – and now she has to pay.

She says it was self defense. That he was some kind of psychopath. But she’s crazy if she thinks I’ll ever believe that.
Now she’s my prisoner, and I just have to decide what to do with her. My wolf wants to ravage her, dominate her, mate with her… but I’ve got to stay in control. I need payback to avenge my brother.

This is a wolf shifter standalone book with a happily ever after ending.
