Ben's father is in prison and his mum, a former child genius, is barely hanging on to her sanity. When Ben and his classmates are nearly killed in a coach crash in Belgium, Ben starts to experience flashbacks: visitations to the brutal start of World War 1 and the uncertain world of Corporal Sam Lyle. Is Ben going mad too, like his mum, or is there another reason why he finds himself in a war zone in 1914? Who is the spectral figure that haunts both the boy and the soldier? Do angels exist?
