Query: The Suicide Jump

I think that Jumping the Nail is one of the greatest books I have ever read. It is a story about a group of friends who find it thrilling to jump off of this 20 storie high rock into water below. The girl that you are reading through the eyes of tries to stop one of her friends from jumping off the rock because she thinks to do that is to mark your own grave. It is a very chilling book and since I only kind of liked it I gave it a 4 stars rating.
