Hannah made her indie directorial debut with last year’s After Everything.

Turtles All the Way Down follows “a 16-year-old a girl with OCD, who discovers through her friend that a billionaire construction magnate has gone missing in the wake of fraud investigations. Tempted by the reward of $100,000 for information leading to the billionaire’s arrest, the two begin a search for the missing billionaire.”

“Turtles All the Way Down” was published in 2017, marking John’s first published work since 2012′s “The Fault in Our Stars.”

“This is my first attempt to write directly about the kind of mental illness that has affected my life since childhood, so while the story is fictional, it is also quite personal,” John said about the book.
