I Am Not A Serial Killer is a 2009 thriller novel written by Dan Wells. It is the first installment in the John Wayne Cleaver trilogy. Its sequel, Mr. Monster, was released in 2010 in the UK. The third installment, I Don't Want To Kill You, was released in January 2011 in the UK.
Wells has stated that he wrote the book with himself as the target audience and that although "a teenager protagonist means the book is [young adult]", the book "is 'adult' enough that different markets are treating it very differently: in the UK it’s a YA horror, in Germany it’s an adult thriller, and in the US it’s being marketed to both audiences."
