R.L. Stine is the Stephen King of kid's horror. His Goosebumps series has been scaring the daylights out of kids for almost 20 years now, and he has branched out into other Goosebumps series (Horror Land, Hall of Horrors) and a television series based on the novels.
The Beast from the East is like reading a demented version of the old nursery song, Teddy Bear's Picnic (also referenced in the story). Twelve year-old Ginger, her ten year-old twin brothers Nat and Pat, and their parents go on a camping trip one summer. While their father sets up the campsite, Ginger and her brothers go exploring and end up getting lost in the woods, where they come upon a group of big, blue, furry bearlike beasts that want to play a game where the winners get to live, but the losers get eaten. There are a lot of rules - can they figure them all out and get back to their parents, or will they end up as dinner?
