I have spent what seems like countless sleepless nights delving into their eerie world, pulling an intriguing piece of gel from that diabolic cake called Five Nights at Freddy’s.
And the result, I be proud to say, is that there are definitely a total of eleven main 'Five Nights at Freddy’s' books, all authored by Scott Cawthon and Kira Breed-Wrisley. This includes the original four-part 'FNAF: The Silver Eyes' series, the 'Fazbear Frights' short story collection which is made up of five individual books, and their two guidebooks 'The Freddy Files' and 'Security Logbook'.
However, there is always the chance that new adventures in FNAF will emerge, so keep watching the horizon!
