Years ago, in an almost accidental moment of heroism, Ed saved Amy from drowning. Now, in his thirties, he finds himself adrift. He's been living in London for years - some of them good - but he's stuck in a relationship he can't move forward, has a job that just pays the bills, and can't shake the sense that life should mean more than this. Perhaps all Ed needs is a moment to pause. To exhale and start anew. And when he meets Amy again by chance, it seems that happiness might not be so far out of reach. But then tragedy overtakes him, and Ed must decide whether to let history and duty define his life, or whether he should push against the tide and write his own story.
