"Ruins" by Scott Smith

"Ruins" is a creepy tale about a small group of friends, who decide to help out another friend, while on vacation in Cancun, only to find themselves trapped in a nightmare. They stumble onto a hill, in a remote part of the jungle and aren't allowed to leave. What makes it bad, is the hill has it's own presence. One that won't cease until they do.
Very quick read. Left me with strange dreams, but anyone who enjoys a good King novel, will like this book. It might turn you off gardening though.
