Lawrence Block writing as Jill Emerson: Getting Off (USA 2011)

From the Publisher:
SO THIS GIRL WALKS INTO A BAR...
...and when she walks out there's a man with her. She goes to bed with him, and she likes that part. Then she kills him, and she likes that even better.

On her way out, she cleans out his wallet. She keeps moving, and has a new name for each change of address.

She's been doing this for a while, and she's good at it. And then a chance remark gets her thinking of the men who got away, the lucky ones who survived a night with her.

She starts writing down names. And now she's a girl with a mission. Picking up their trails. Hunting them down. Crossing them off her list...
