This is the story of Joshua, Lily, Tommy and Eva: one family with an extraordinary gift - they can all travel through time. But when their parents disappear, Tommy and Eva must work out how to move on. Tommy takes refuge in the past, and a love affair with a woman from a different era keeps him there. Escaping his unhappy life in contemporary London feels like a relief at first. But no one can live two stories. Eventually, Tommy will have to decide where his heart - and his future - really belong.
