To All the Boys I've Loved Before is a 2014 young adult romance novel by American author Jenny Han, first published by Simon & Schuster and released on April 15, 2014.
 Han was inspired to write the book based on her own habit of writing long letters to boys she had crushes on as a teenager.
 The novel was followed by two sequels, "P.S. I Still Love You", released on May 26, 2015, and "Always and Forever, Lara Jean", released on May 2, 2017.
The song was written about Jenny, the aunt of lead vocalist Jonny Hawkins, and Jenna, his sister.
 Jenny suffers from schizophrenia while Jenna has bipolar disorder.
 Following the release of the album in July 2014, the band partnered with Bring Change 2 Mind, The Jed Foundation, The International Bipolar Foundation, Young Minds (UK) and To Write Love on Her Arms.
The Wasp Factory is the first novel by Scottish writer Iain Banks, published in 1984.
 Before the publication of "The Wasp Factory," Banks had written several science fiction novels that had not been accepted for publication.
 Banks decided to try a more mainstream novel in the hopes that it would be more readily accepted, and wrote about a psychopathic teenager living on a remote Scottish island.
 According to Banks, this allowed him to treat the story as something resembling science fiction – the island could be envisaged as a planet, and Frank, the protagonist, almost as an alien.
 Following the publication and success of "The Wasp Factory", Banks began to write full-time and would go on to write several more novels before his death in 2013, including several acclaimed science fiction novels that formed the Culture series.
Better Than Home is the seventh solo studio album by American singer-songwriter Beth Hart.
 Hart's husband and her manager convinced her to work with the production team of Rob Mathes and Michael Stevens, whom she had met when she performed at the Kennedy Center Honors in 2012.
 Hart had worked with Kevin Shirley for her last three albums, but she was persuaded to try a different team and go a different direction.
 The production team challenged Hart to leave behind the darker themes and to "write more about my joy and what I believe in and what my love is."
 Hart was pushed to write songs that came from a different source, from when she was happy or having a good time.
 One song on the album, "Tell Her You Belong to Me", took her a year and a half to write.
