'We swear, on these trees, to always be friends. To protect each other - and this place.' Finding those carved trees forged a bond between Jay and her four childhood friends and opened their eyes to a wider world. But their attempt to protect the grove ends in disaster, and that one day on the river changes their lives forever. Seventeen years later, Jay finally has her chance to make amends. But at what cost? Not every wrong can be put right, but sometimes looking the other way is no longer an option.
