Give Yourself Goosebumps is a horror fiction gamebook series in which the reader chooses the story. All of the books are credited to R.L. Stine, but many of the books were ghostwritten. The books were written from 1995 to 2000, starting with Escape from the Carnival of Horrors, and ending with All-Day Nightmare. There are fifty books in the series, including special editions, and all of them are currently out of print, except for Please Don't Feed the Vampire!, which was made into a Classic Goosebumps book as a tie-in to the Goosebumps film.
