I am so in love with the character John Cleaver....this whole series is turning into quite a wonderful development. From your first introduction in I am not a serial Killer now to Mr.Monster you get to watch John develop as a teen and also fight the monster that is inside of him. Is the girl of his obsession really a obsession or is he falling in love with her? can you kill what you love? how long can he fight of his urges? is he really the monster or a demon slayer? the modern day male Buffy with a slight edge of sociopath. I really enjoyed this book, simple but layered with dark humor, continuity, interesting plot twist and freshness.
