Twilight is a series of four fantasy romance novels, two companion novels, and one novella written by American author Stephenie Meyer. Released annually from 2005 through 2008, the four novels chart the later teen years of Bella Swan, a girl who moves to Forks, Washington, from Phoenix, Arizona and falls in love with a 104-year-old vampire named Edward Cullen. The series is told primarily from Bella's point of view, with the epilogue of Eclipse and the second part of Breaking Dawn being told from the viewpoint of character Jacob Black, a werewolf. A novella, The Short Second Life of Bree Tanner, which tells the story of a newborn vampire who appeared in Eclipse, was published on 2010. The Twilight Saga: The Official Illustrated Guide, a definitive encyclopedic reference with nearly 100 full color illustrations, was released in bookstores in 2011. In 2015, Meyer published a new novel in honor of the 10th anniversary of the book series, Life and Death: Twilight Reimagined, with the genders of the original protagonists switched. Midnight Sun, a retelling of the first book, Twilight, from Edward Cullen's point of view, was published in 2020.
