Regeneration, one in Pat Barker's series of novels confronting the psychological effects of World War I, focuses on treatment methods during the war and the story of a decorated English officer, poet Siegfried Sassoon, sent to a military hospital after publicly declaring he will no longer fight.

Yet the novel is much more. Written in sparse prose that is shockingly clear, the descriptions of electronic treatments are particularly harrowing, it combines real-life characters and events with fictional ones in a work that examines the insanity of war like no other.

The trilogy is concluded in The eye in the door and The ghost road.
