The Regeneration Trilogy by Pat Barker comprises three novels — Regeneration, The Eye in the Door and The Ghost Road — set during the first world war.
The novels are about the WWI experiences of poets Siegfried Sassoon, Wilfred Owen and a fictional third character, Billy Prior.
Pat Barker sensitively explores the mental health problems caused by the horrors of war. All three characters in these novels spend time in Craiglockhard, a Military hospital, under the care of a psychiatrist, Dr Rivers. The telling of their stories is human, moving and absolutely compelling. If you have been scared off by the subject matter, or perhaps like me, thought you were not a reader of war fiction, I encourage you to reconsider. This is perhaps the most powerful series I have ever read. I thoroughly recommend it.
