Who wrote the young adult novel "The Fault in Our Stars"?

The story behind the answer

John Green wrote the young adult novel The Fault in Our Stars (2012), a witty and heartbreaking story about Hazel Grace Lancaster and Augustus Waters, two teens navigating love and mortality. Inspired in part by Green’s friendship with cancer patient Esther Earl, the book became a bestseller and a 2014 film, praised for its humor, honesty, and sharp dialogue.

To avoid confusion: Stephenie Meyer wrote Twilight (vampires), Suzanne Collins wrote The Hunger Games (dystopia), and Stephen Chbosky wrote The Perks of Being a Wallflower (epistolary coming-of-age). Memory tip: “Green = life,” fitting a story about finding meaning and love even amid illness.
