We Are All Completely Fine by Daryl Gregory
Are you a Supernatural fan? Imagine Dean Winchester going to a group Therapy session with four victims. (each from a different season of the show.)
Yep, that's how I felt about it.
Of course Harrison is no where near as Sexy, funny or sarcastic as Dean, but the whole set up felt like a Supernatural story.
It's short 182 pages. So it won't take long to read.
