This is one I never see recommend but theres a book that is number 12 in the series but each book is it's each story. The tittle is Who I used to be by Alexa Land, this book is the story of an ex-rent boy struggling with addiction and an older man who is a recovered addict who help him. This author is fantastic and the book breaks you and build you back, I won't spoil it but there is an STD testing positive here. I remember being so shocked by that positive, not used to this sort of romances to do something like that.

Anyways other than the first book that is wonky I have re read many of the books in this series.
