Black Gypsies

This was offered to me in exchange for a review from some program (not directly from the author) but I since have not been able to figure out from where! It was pitched to me as crime fiction, which it is not. It is however, about two friends that commit crime together. Goodreads has it just tagged under just ‘crime,' which is right though! 
So, this was not my typical kind of read, especially with me going into it expecting some kind of mystery/investigation to be taking place. However, it was still good, and I'm glad to read in a perspective I do not personally have. 
Two friends in Chicago spend their time stealing parts off cars, selling them to junkyards, and taking from various victims which they call stains. When one of their grabs goes a little too far, against someone they shouldn't have, things take a turn for the worst. They'll have to decide whether or not to run or fight. 
The novel was written well, but the ending did leave a bit to be desired for me. Was there remorse? Did they feel nothing? Did they go back to their old ways? Or did they actually get out? Sometimes ambiguity can be good, but I just wanted a tad more. Personally a 3/5* for me, I'd recommend.
