It has been quite awhile since John Green has released any press news about a new book. John Green has publicly announced his new book titled, Turtles All the Way Down, at VidCon 2017. It is said to be released on October 10th, 2017.
According to EW,
Publisher Dutton Books, an imprint of Penguin Young Readers, describes the book as being “about lifelong friendship, the intimacy of an unexpected reunion, Star Wars fan fiction, and tuatara. But at its heart is Aza Holmes, a young woman navigating daily existence within the ever-tightening spiral of her own thoughts.”
