Nicholas has plenty of reasons to feel unstable: he's fifteen, the child of divorced parents, living with his mostly absent dad in the bleak Chicago suburbs, and an outsider at school. Then, one day in geometry class, he forgets how to breathe. The doctor says it's just panic, but Nicholas suspects that his real problem might not be a psychiatric one: maybe the Greek god Pan is trapped inside his body.

As the paradigm for his own consciousness crumbles, Nicholas and his friends hunt for answers why - in art, music and literature - as they reach for a life beyond the confines of where they've grown up and what's expected of them.

Thrilling, surprising and startlingly funny, Pan takes us inside the human psyche, where we risk discovering that the forces controlling our inner lives could be more alien than we want to let ourselves believe.
