Five Nights at Freddy's: The Silver Eyes (2015) by Scott Cawthon.

About

 * The games and the books should be considered to be separate continuities, even if they do share many familiar elements. So yes, the book is canon, just as the games are. That doesn't mean that they are intended to fit together like two puzzle pieces. [...] The book is a re-imagining of the Five Nights at Freddy's story, and if you go into it with that mindset, I think you will really enjoy it but is sadly not canon so the book is in a au.
