The Life and Words of Esther Grace Earl," published by Dutton Juvenile on Jan. 28 (Twitter via @laurenmyrtle).

The trailer for the best-selling young adult novel, John Green's "The Fault in Our Stars" came out on Wednesday to a haze of hashtags and tears, but it's not the only new release of importance to Green and fans of the novel.

Esther Earl, the girl to whom "The Fault in Our Stars" was dedicated, died of thyroid cancer in 2010.  Her memoir, titled "This Star Won't Go Out: The Life and Words of Esther Grace Earl," was also released Wednesday, and includes an introduction by John Green.

This Star Won't Go Out is also the name of a foundation directed by Esther's mother, Lori Earl. The organization provides financial assistance for families with a child living with cancer. The foundation has made contributions of over $125,000 since it began in 2011. Green remains very involved in the foundation.

The book is comprised of diary entries, e-mails and blog posts. On his Facebook page, Green heavily endorsed the book. He wrote, "Esther was an extraordinary writer, and the book is so great. I cannot recommend it enough."

Green and Esther met not through the Internet, but as a result of the Internet, proving that amid the pornography and the viruses, good things can happen on the Internet. Esther knew Green from his novel "Looking for Alaska" and Vlogbrothers, his YouTube channel with his brother Hank Green. They met in person at a convention for Harry Potter fans in Boston.

While "The Fault in Our Stars" was dedicated to Esther, Green never intended to appropriate her story, and Hazel, the novel's narrator, is distinctly different from Esther, according to both Green and Esther's family.

Esther wanted to be an author as a child, and her father said, "Now, she is."
