This was by far the most explicitly gruesome book I've ever read, but in such a good way. I picked this up when I saw Stephen King recommended Cutter's other book, and it didn't disappoint. Deep Blue Sea meets The Shining meets The Thing, and I was either totally grossed out or totally terrified the whole time. 
 Cutter does a great job tapping into your individual, run-up-the-stairs-when-it's-dark-in-case-someone-is-chasing-you fears, and that's not something I feel with a lot of horror writers. 
 Four out of five stars because some of the plot elements were just a little too "come onnn, really?" (the dumb character who goes into the dark basement unarmed when he's almost positive that's where the bad guy is lurking in a horror movie).
