Ruin Him by Scarlett Finn

Her actions did more than end his life.
On the run, in hiding, Tulsi Tern can’t focus on the past. Learning how to survive on her own without skills or allies is tough. She’s vulnerable without her protector and struggles to make enough money to live.
Given her history, trusting isn’t easy. So when Amsterdam comes along and offers sanctuary, Tulsi takes time to let down her guard. Just as she begins to relax, her past rears its ugly head, endangering her new friends.
One beacon of light is snatched away by someone who demands justice. Until she surrenders to her punishment others will pay the price for her crime.
