If I Stay is a young adult novel by Gayle Forman published in 2009. The story follows 17-year-old Mia Hall as she deals with the aftermath of a catastrophic car accident involving her family. Mia is the only member of her family to survive, and she finds herself in a coma. Through this coma, however, Mia has an out-of-body experience. Through this, she is able to watch the actions around her, as friends and family gather at the hospital where she is being treated. We follow Mia's stories and the unfolding of her life through a series of flashbacks. Mia finds herself stuck between two worlds; the world of the living, and the world of those who have moved on. Mia realizes that she must use her past and her relationships to make a decision for her future. Her options are to stay with her grandparents and the love of her life, Adam, or to move on and avoid the pain of living without her mother, father, and little brother. The novel received positive reviews from the young adult audience, and Summit Entertainment optioned it in December 2010, for a 2014 film adaptation.
A novel continuing Mia's story, Where She Went, was published in April 2011.
