Book excerpt: Nicola Lancaster is spending her summer at the Siegel Institute, a hothouse of smart, intense teenagers. She soon falls in with Katrina (Manic Computer Chick), Isaac (Nice-Guy-Despite-Himself), Kevin (Inarticulate Composer) . . . and Battle, a beautiful blond dancer. The two become friends--and then, startlingly, more than friends. What do you do when you think you're attracted to guys, and then you meet a girl who steals your heart? A trailblazing debut, reissued with an introduction by acclaimed author David Levithan, and copious back matter, including three graphic novel stories by Sara Ryan (and artists Steve Leiber, Dylan Meconis, and Natalie Nourigat) about the characters.
