Slip

SLIP is a Young Adult Science Fiction novel about transgender identity.
All 17-year-old Xavier can think about is graduating high school and moving to a place where no one will look twice at him. Everyone at school thinks he's gay, but he'll take the rumors over everyone knowing his truth. For 17-year-old Natasha, life's pretty good. She's popular, has two best friends, and is dating the captain of the football team, the object of Xavier's crush.
After witnessing a traumatic event at a Halloween bash, Xavier and Natasha experience a night which forces them to view the world through each other's eyes. Soon Natasha is faced with the grim realization that her identity dictates how the people in her life treat her. Meanwhile, it's a concept which Xavier knows painfully well. As they struggle to accept certain truths of their realities, they can tell no one what's happening to them. No one would believe them anyway, because they barely believe it themselves.
