All the Bright Places is the first Young Adult novel by Jennifer Niven. Published on January 6, 2015 by Knopf Publishing Group, All the Bright Places received positive reviews from The New York Times, Entertainment Weekly, and The Guardian, and was the winner of the 2015 Goodreads Choice Award for Young Adult fiction. A film adaptation starring Elle Fanning and Justice Smith, for which Niven wrote the script, was released on Netflix in 2020. The novel has been compared to the likes of The Fault in Our Stars and Eleanor & Park.
Niven decided to transition from adult fiction to YA after feeling "depleted and ready—creatively—for something new and different." Her inspiration for All the Bright Places was drawn from her own experience of being in love with someone who took his own life. The novel has been praised for its conscientious treatment of mental illness, trauma, and suicide.
