I love books that are a little bit different and this series is certainly that. 
 I can't say I loved the conclusion though because there were things I'd like to change. 
 (view spoiler)[ I had trouble understanding how Karissa could go back to him after he killed her mother when he knew how much it would hurt her. It was also around that time I decided that Maria, Naz's wife that died, was the love of his life. It felt like Karissa was a distant second. The ending tried to change my option when he visited her grave and found some closure, but ultimately it left me feeling like there was something missing in their relationship. (hide spoiler)] 
 However, overall, I really did enjoy it.
