Diary of an Oxygen Thief

I first heard of this book close to ten years ago and have been desperate to read it since seeing the opening page posted on Tumblr. I found this book compelling to begin with, I could see the foundations of the narrator being unreliable, narcissistic and a misogynist, well written too. Obviously the point of the novel is that the narrator is a dick and his ‘diary' is a love letter to his shitty behaviour. I put the book down on page 81, the beginning of chapter 3 and the final chapter of the novella (?), once I jumped back in I felt bored and almost robbed up until pages 130-151 which gave a sense of excitement before ending abruptly (he did warn us of this).

I'm torn, in one sense I feel that there could have been so much more yet I fear that could also have ruined it. I'm very much keen to read the following novels and hopefully by the end of the currently trilogy I can return.
