Please note, this book contains a gay character or two ( no sex scenes or explicate material, however). If you are homophobic I do not recommend this book.

There have been a few random 0.5 ratings from what I can only assume are from people who don't like a gay mc or dislike the genre. I just ask that you read and judge the book for yourself.
