I like this book. The main characters were likeable. The side characters (Pietro, Miles, Thomas, etc...) were likeable. Rob and Alex's mother were *not* but alas, you can't have everything, tight? I'm a little divided about Dorian. 
 On the one hand, I sort of wanted his membership revoked, but on the other, I feel like there's more going on with him than just his 'pain slut' reputation. That, of course, remains to be seen. Regardless, he should have left well enough alone once he learned Leo was off the market. Even if he believed (for whatever reason) that Leo was trying to change himself for a partner, not in the lifestyle (assuming he thought that when he heard Alex was not part of the community) he could have, at the very least, observed them together before making any sort of decisions and taking any sort of overt action. 
 Anyway, enough about Dorian... 
 It was nice to see Alex come out of his shell and come into his own. His family (with maybe the exception of his father even if it did take him a while to grow a pair) were just a waste of oxygen and it's understandable how difficult it must have been growing up in that kind of stifling atmosphere. 
 Leo, on the other hand, is still dealing with a debilitating loss, and I was pleased to see that so accurately portrayed. The death of a partner is not so easily moved on from, so I was glad that the author didn't have Gabe's death be more recent. 
 Overall this was a well-done story, with well thought-out three-dimensional characters.
