A tough one to review. The writing was really good, the characters especially all felt incredibly real. Alex is an easy guy to relate too, but everyone we spend more than a moment with in the book feels like their own person - especially Diane. 

I think the horror elements were well executed, tension was left to build appropriately and one or two scenes were particularly visceral. 

The ending I'm a little unsure of. I think I know what the author was going for, but it fell a little short, or was perhaps murkier than I would personally have liked. 

Going to look at more from this author though, and a short read definitely worth giving a chance.
