Twilight is a popular young-adult vampire romance series written by Stephenie Meyer. It tells the story of 17-year-old Bella Swan who moves to Forks, Washington, and falls in love with a dangerous young man who is not what he seems. The series contains four novels, and a draft of "Midnight Sun" which is an unfinished alternative version of the first novel, but from Edward's perspective.

The Host is a science fiction/romance novel also by Stephenie Meyer. The Host introduces an alien race called "souls" who take over Earth and reside inside the bodies of their human hosts, and describes one soul's predicament when her host body refuses to cooperate with her takeover. The author describes it as perhaps the only love triangle involving just two bodies.

A retelling of the events of Twilight, but written from the perspective of Edward Cullen as opposed to that of Bella Swan. Meyer has stated that Twilight is the only possible book from the series that she plans to rewrite from Edward's perspective.

As of August 28, 2008, Meyer has halted the writing of Midnight Sun indefinitely due to the illegal leak of 12 chapters of the unfinished manuscript. She has made the leaked chapters available on her website in fairness to her readers, now that the novel has been compromised before the intended publication. The release date of the book has been postponed indefinitely.
