On an island off the coast of France, six teenagers come together for a summer of desire and discovery until one of them vanishes forever, leaving the rest with an enduring mystery. 

Tell me, do you know why the most beautiful love stories must always end badly?

In the summer of 1985, on a scruffy resort island off the coast of France, six teenagers, five boys and one girl, band together for a final golden season before adulthood. Their days are drenched in sun and freedom, and their nights simmer with secrets, jealousy, and longing. Philippe is drawn to Nicolas, the quiet new boy who sees him in a way that no one else does.

As their bond deepens, part of Nicolas remains unreachable, until a sudden tragedy brings their summer to a brutal end. The Summer Boy is a lush and unforgettable autobiographical tale, capturing the ineffable summers of youth in amber.

Celebrated novelist Philippe Besson has shaped his memories into an aching meditation on how one summer night and one fierce connection, can echo across a lifetime.
