I'll admit that for the first half of this book, I was bored. 
 Watching Lindsay and Valentine trying to cope after a breakup annoyed the hell out of me. In fact, I only really liked the ending even though I wasn't really rooting for these two even in the first book. They were a toxic clash of two very terrible but unbelievably funny and likable characters. 
 (view spoiler)[ What I liked the most was the Valentine's reconciliation with his family and honestly understanding how he really felt about Olly. He matured really well as a character at 26 instead of remaining that ridiculously impulsive and easily angered snivel-ling 19 year old. Lindsay didn't feel like he changed much to me but he did become a bit humbled after getting fucked over a little during his travels. But damn, dude seriously did a lot of drugs though.

 In the end, it felt like they really deserves each other since they were much more matured.
