An Army of Skin

Normally this kind of psychological is it all in his head type of stories feel like they've already been written a 1000 times to me but this one was really engaging even though the main character has that one enormous flaw that made it so I couldn't root for him at all, his name was Trevor, an unforgivable sin in my book.

On a more serious note, if you're looking for a quick read that has just the right balance between gore, character building (Mr. King was actually a pretty compelling character) and action look no further.
