Rules of My Best Friend's Body, a novel

Arty and Larissa have the perfect relationship. She’s beautiful and afraid of her own popularity. He sits alone and draws comics. They're both social misfits—him obsessively, her secretly. They go to different schools, but they trade late-night phone calls and between-class meetings in Hebrew School. They never run out of things to say.

Then one night, one of their common friends attacks Larissa in the darkest and most unforgivable of ways—the same night that Arty was planning to kiss her.

Larissa’s world falls into a tailspin, and at the same time Arty's own life threatens to explode. He wonders if being a guy is just like being a time bomb. His own body—his own head—feels like a traitorous enemy.

As Arty and Larissa find themselves betrayed by their own feelings and torn apart by circumstance. What will this mean to their group of friends? Who can he trust? Will Larissa ever be the same—and can Arty ever feel the same about her again?
