It started off really funky, and the overall story is good. Just a few things stand out to me that I wish had been different. 
 - I'd be more comfortable if the book didn't include child murder, especially one so gory. 
 - The ending feels unfinished and hurried. It's like the author got tired of the story and just wrapped up. The last few chapters are a mess. 
 - This book goes from a couple to a menage. With one of the men being bi, and the other being open to being bi, I was disappointed that all they shared was some kisses and cock-rubbing. And in a threesome like this, where they all are committed, I missed the ass-play. All we were given was some cock-sucking and vaginal sex with the girl. Rather tame for an author who warns about explicit and delicious sex...
