Every summer Teresa follows her father to his childhood home in Puglia, down in the heel of Italy, a land of relentless, shimmering heat, centuries-old olive groves and taciturn, proud people. There Teresa spends long afternoons enveloped in a sun-struck stupor, reading her grandmother's cheap crime paperbacks. Everything changes the summer she meets the three boys who live on the masseria next door: Nicola, Tommaso and Bern - the man Teresa will love for the rest of her life. Raised like brothers on a farm that feels to Teresa almost suspended in time, the three boys share a complex, intimate and seemingly unassailable bond. But no bond is unbreakable and no summer truly endless, as Teresa soon discovers. Because there is resentment underneath the surface of that strange brotherhood, a twisted kind of love that protects a dark secret. And when Bern - the enigmatic, restless gravitational centre of the group - commits a brutal act of revenge, not even a final pilgrimage to the edge of the world will be enough to bring back those perfect, golden hours in the shadow of the olive trees.
