This is one of those books that you must read with ALL the lights on, your back to the wall, and someone else in the room with you. Once I started this book, I kept looking over my shoulder to make sure nothing was coming after me! This book reminded me of the movie House on Haunted Hill, but in a teen version.I don't why I continue to read scary books even though I know they scare me. But holy cow! This book is written amazingly and just creeped me out to the bone. I mean, it really shook my up. Mr. Gates did an amazing job in scaring the begezzus out of me. And I am sure he will do just a fine job doing that to everyone else. His story line is filled with non-stop mystery, action, and plenty of raising the hair on the back of my neck moments. The plot line slowly creeps out on you as you read. Nothing is what is seems, but before you know it, Mr. Gates writing jumps out on you so fast!
