Blackbirds by Chuck Wendig.
This chick Miriam can tell with one touch the means, the methods, and the EXACT moment you will die. So she is a scavenger. Follows you around, waits for Fate to do its thing, and then she cleans you our - money, credit cards, things she needs - and keeps moving on. She used to try and stop things from happening but in every case, she wound up being the catalyst for the event itself. So she just lives with her knowledge, lives in a very dark place.
There is a male protagonist too, a scummy con man who stole a shitload of meth from two hired killers and he wants to use her gifts to help him hide out. Find someone about to die, or even better, die on a trip or vacation, then cop a squat at their house while no one knows.
It is dark and seriously fucked up writing, but it is strangely entrancing. She is vile and loathsome, and finding any sympathy for her is very hard, even less for Ashley (the dude). But it is different and unique and it certainly has my attention.
Like it. Don't. You just never know.
