Dan Riley is a major in the British Army. After a six month tour of duty in Afghanistan, he is coming home to the wife and young daughters he adores. The outside world sees those reunions as a taste of heaven after months of hell. But are they? Can a man trained to fight adjust again to family and domestic life? And how will the family cope, if he can't? How much, indeed, can Alexa, Dan's wife, sacrifice her own needs and fulfilment to serve his commitment to a way of life that demands everything not just of him, but of her and the children as well?
