I kept clear of Dog Cullen. Till the summer we turned seventeen, the summer the dolphin came to Carrig Cove...

Donegal, 1976

When a dolphin takes up residence in Carrig Cove, Emer and her best friend, Fee, feel like they have an instant connection with it. Then Dog Cullen and his sidekick, Kit, turn up, and the four friends begin to sneak out at midnight to go down to the beach, daring each other to swim closer and closer to the creature...

But the fame and fortune the dolphin brings to their small village builds resentment amongst their neighbours across the bay, and the summer days get longer and hotter... There is something wild and intense in the air. Love feels fierce, old hatreds fester, and suddenly everything feels worth fighting for.
