It is January 2017. E.G. Rawlings, a noted foreign correspondent forced into retirement after a serious injury in the field, arrives by boat at a vacant mooring on the Thames. To his surprise, he finds it is owned by an old friend from Afghanistan, Isobel Mallinson, the widow of a British diplomat. On learning that Rawlings is now writing an account of his war experiences, Isobel allows him to use her mooring for the year he needs to finish his memoir. During the months that follow, Rawlings, suffering from PTSD and in terrible emotional and physical pain, finds solace in the peaceful life of the river and the community he finds there. Although a loner by nature, he becomes particularly close to Marnie, a middle-aged art teacher with a fragile heart who lives near him in the boathouse. He begins to tell Marnie his story, explaining the unexpected events that have resulted in what he calls 'turning points' in his life, taking him in surprising and new directions. Little does the jaded reporter realise that another turning point is just around the corner that will not only profoundly affect his life, but also the lives of all those around him.
