As construction begins on the Golden Apple Amusement Park, Aaron Peterson is becoming increasingly worried about his father. Working late nights in his study, Aaron's dad seems to be fraying at the edges - pushing, and sometimes breaking, the laws of engineering with his new schematics. And with the added pressure he's under to complete the park by this summer, Aaron can't help but feel his father's inventions are doomed to end in tragedy once again.

Aaron Peterson feels like he's trapped in a recurring nightmare. After moving halfway across the world to flee his father's latest theme park failure, yet another disaster has occurred: A roller coaster car jumps the tracks at the Golden Apple Amusement Park, resulting in the death of his friend, Lucy Yi.

It's been four months since Nicky Roth has seen his best friend and neighbor, Aaron Peterson. Aaron's father, a reclusive theme park designer, told the town that Aaron and his sister Mya are living with a relative far away, but Nicky can't seem to accept it. Plagued by terrifying nightmares of robotic mannequins, rotting theme parks, and a dark basement, Nicky teams up with his friends from school to find out what really happened to Aaron and Mya. Together, they start piecing together a picture more disturbing than they could have imagined.

To avoid confronting an ugly truth, Nole falls prey to a monster that punishes past transgressions. Growing weaker by the day, 9-year-old Jake looks back on the time before he was sick, imagining life as if he were well again. And, forever desperate to prove his worth to his arrogant brother and distant father, Toby chases victory at an arcade game with horrifying consequences. In this sixth volume, Five Nights at Freddy's creator Scott Cawthon spins three sinister novella-length stories from different corners of his series' canon.

Aaron Peterson has never had it easy. As the son of a famed and eccentric theme park designer, his life has been one move after the next as his father chases new jobs in countries around the world. Aaron has watched rides and attractions of all kinds start with a blueprint on his father's desk, and end up a towering, larger-than-life creation to marvel park-goers. That is...until something really, really bad happened on his dad's latest job in Germany. Something worse than the accidents that had happened before. Something that Aaron and his family are desperately trying to forget.
