Dan Wells' I Am Not A Serial Killer is kinda fantastic.
It's shelved in horror, but while it's horrifying, it's not terrifying if that makes any sense.
John is a boy who knows he has many of the early indicators of a budding serial killer, so he's trying so very hard not to be one. Then someone else starts leaving bodies all over town.
Wells makes a serial killer's mind make sense, and there's something quietly horrific about that.
The premise can sound similar to that of the tv show Dexter (based on the book Darkly Dreaming Dexter, which I haven't read) in that the protagonist has serial killer tendencies, but the two really aren't the same at all.
Maybe it's just because of differences in the media, or maybe it's the actor but I never really got Dexter. Wells really brings you in with John. He shows you the emotions in a boy who supposedly has none and it makes the book great.
I Am Not A Serial Killer is the first in a series of three books. The second is Mr. Monster, and the third is I Don't Want to Kill You.
I have also read Mr. Monster. I killed it (:D) in two days, and then the day after, I woke up and went "What in the Fuck did I just READ?!" I haven't read the third yet, but I plan on it.
