Keith Deininger's WITHIN just made my list of best horror for 2015. It's moody, the writing is crisp and evocative, and the author provides just enough detail to make his scenes creepy and disquietingly evocative.
WITHIN is more than a haunted house story - it's a haunted town story, as the entire area of Mesa Rapid, where the spooky Upshaw Mansion is situation, is brimming with ugly history and spilled blood. In fact, Deininger's telling of Mesa Rapid's history was one of the highlights of the book for me.
Some readers might be a bit turned off by the slow build nature of the horror here, but once things start clicking into place the story becomes absolute dynamite, and there's atmosphere to spare. The finale is a top-notch finish, and one of the more unsettling endings I've come across in recent memory.
