A teenager who died from cancer sent a heartbreaking letter to the future revealing her hopes and dreams of true love.
Esther Earl, who died from thyroid cancer in 2010 at the age of 16, inspired John Green's novel The Fault in Our Stars, which has been made into a film.
Her parents Lori and Wayne have now published their own book, This Star Won't Go Out: The Life & Words of Esther Grace Earl, a collection of Esther's drawings and notes along with family stories.
One of Esther's letters in the book was written when she was 14, to her 17-year-old self.
The teenager, from Massachusetts, sent the letter to her parents to make sure someone would read it if she had already passed away.
The letter, which her parents received a year after Esther died, read: "...future me, i hope you're doing better than present me.
"If you haven't done something amazing, don't forget to try. The worst that can happen is you fail, and then you can just try again until you succeed."
Esther, who also posted several videos of herself on YouTube, also talks about her parents and siblings, asking her future self if her mum has gone back to teaching and imagines her brothers and sister growing up.
And despite her battle, Esther's real life mirrored the novel she inspired as her mind turned to her love life.
She wrote: "What about, oh those silly things, boys? have you been kissed yet? Amidst allllll the health problems and psychological problems, I still want to find a guy I like, who likes me back. i can't help it, it's just one of those stupid things i want."
