I think the book would have been better if it started when Dusty and Bliss were a few years older and turned into a new adult book rather than Bliss being a teenager. The story could have skipped over the beginning years without a problem. It would have made the book seem a little more age appropriate if they were a little older in terms of their relationship progression. 
 Dusty (Thomas) was a complete ass but Bliss was sweet even if she wasn't as sweet as her friends and family thought, since she lied to everyone. She also needed to stand up for herself more and get some clue about the fact that Dusty is on a downward spiral and start trying to help him. She never even asks if he's OK or why he takes drugs. Instead she just lets Dusty walk all over her feelings because she "can't change him". 
 However, I have no idea why Bliss loved him. Since past behaviour is the best way to predict future behaviour I can't imagine when he will ever be trustworthy. He knew that what he did was wrong and he was hurting Bliss, that he was disrespecting her but he didn't care. He just kept doing whatever he felt like. He said he loved her but rarely acted like it. The majority of the time he completely disgusted me. The rest of the time I felt sorry for him. 
 In the end, I was able to keep reading because of how young they both were. I kept hoping they would grow up and start to change.
