Reader beware The biography of R. L. Stine, author of the hugely popular Goosebumps series, is a scary-good time R. L. Stine began writing stories at the age of nine, after finding a typewriter in his family's attic. (Was it a haunted typewriter? Who can be sure?) Often referred to as the Stephen King of children's literature, R.L. has created some of the scariest books to have ever been passed around a campfire, leaving readers wide awake at night. With over 400 million copies of his horror fiction novels sold across the world, R.L. Stine is one of the best-selling authors in history.
