Seventeen-year-old Leopold Berry is seeing weird things around Los Angeles. A man who pops a tooth into a parking meter. A glowing trapdoor in a parking lot. A half-mechanical raccoon with its tail on fire that just won't leave him alone. Every hallucinatory moment seems plucked from a cheesy 1990s fantasy TV show called Max's Adventures in Sunderworld-and that's because they are.

 

Not a good sign.

 

In the blurry weeks after his mother's death, a young Leopold discovered VHS tapes of its one and only season in a box headed for the trash-and soon became obsessed. Losing himself in Sunder was the best way to avoid two things: grieving his mother and being a chronic disappointment to his overbearing father. But when the strange visions return-at the worst possible time on the worst possible day-Leopold turns to his best friend Emmet for help. Together they discover that Sunder is much more than just an old TV show, and that Los Angeles is far stranger than they ever imagined. And soon, he'll realize that not only is Sunderworld real, but it's in grave danger.
