this was a dark romance- ML was stalking FL for 8 months before meeting her again. she didn’t not notice. She has a bad past

multiple scars with the word thief written on her stomach

but he is a serial killer that likes the skin ppl and she is a little messed up. they love each other and they apparently have the same blood kinks so good for them. Anyways- pretty good but crazy. I feel like i’ve read another book by this author but can’t find it.
