Abi Campbell's brother Jack has everything to look forward to: just 18 and finishing his A-levels, he's a star student with a prestigious university scholarship awaiting him. The youngest of five, Jack has largely been raised by Abi after their mother died, and she adores him.

The Campbells' world is turned on its head when, one summer morning, the police arrive to arrest Jack. His childhood friend Katie has accused him of a terrible crime. The worst one.

Rumours about what happened swirl through their small seaside town, turning friends against friends and brothers against brothers. Only Abi stands by Jack while it seems the rest of the world point fingers. She knows he is innocent. He has to be. He's her golden boy. And blood is thicker than water.

But can you love someone too much?
