The In-Between, by Barbara Stewart. When 14-year-old Eleanor Moss survives a terrible car accident, she gains entry into an in-between world inhabited by Madeline. Unlike awkward, unpopular, unhappy Eleanor, Madeline is beautiful and fearless. As her secret kinship with Madeline becomes more and more central to Eleanor’s life, the mystery of who she’s really talking to—a ghost? a friend? a sister? a hallucination?—becomes all the more troubling.

Fangirl, by Rainbow Rowell. In a genre crowded with the paranormal, Rowell’s deceptively simple, emotionally powerful books stand out. Fangirl is the story of Cather Avery’s first year at college. Her childhood was defined by her bond with her twin sister and writing fan fiction about a popular series of children’s books. Widely encouraged to let both of these things go as childish and branch out in college, she is left with little idea of who she is in their absence, and how to go about rebuilding her life.

Invisibility, by Andrea Cremer and David Levithan. The story of Stephen and Elizabeth is cowritten by two of young adult literature’s best-selling authors, who alternate writing the characters’ first-person narration. Born invisible, Stephen has lived 16 years unseen by anyone, including his mother. Elizabeth is the first person to see him and speak to him, and theirs is both a bittersweet love story and a search for the supernatural truth behind Stephen’s existence.
