Sebastian Gerald. Berkley's Bastards, #5

A home invasion took Toby Hayden's family, all but her grandfather, away from her when she was seven. After the horrors she'd witnessed that day, Toby trusted no one. Sebastian Gerald had recently lost his wife and child from a mob hit meant to get his attention. He had turned down their "job" offer, and they were coming for him. Laying low was the prudent thing to do. When a man came into the bar looking for someone related to a man named Anderson, Toby knew the family, but there was no way she'd give the stranger any information.
When he put his hands on her the first time, Toby warned him not to do that, but when he put his hands on her again, it was the last warning.
