“Turtles All the Way Down has all the hallmarks of John Green's work: an elusive mystery, offbeat but endearing friendships, and a healthy worship of nerd culture (this time Star Wars fan fiction). This long-awaited new novel is an intimate examination of living with mental illness, an issue which with Green shares a personal relationship. Avid fans can expect to laugh, cry, and pass this book on to everyone they know; Green's words are the kind that are best shared.”
