Summary

Sisters Riley and Alice, now in their twenties, have been returning to their parents' modest beach house every summer for their entire lives. Every summer growing up, in the big house that overshadowed their humble one, there was Paul, a friend as important to both girls as the place itself, who has finally returned to the island after three years away. But his return marks a season of tremendous change - a simmering attraction, a serious illness, and a deep secret all collide.
