Lit crit. This slim book provides the reader of Pat Barker's trilogy of WW I Regeneration books with background on the author, a history of the reception of the book, and some insight into the characters. It seems pretty clear that Barker intended W H R Rivers to be the hero of her books and not Siegfried Sassoon, although he and other play important parts in the story.
Excellent piece of anti war literature. I read it almost 20 years ago when it was first published. It was just as fresh and stirring the second time around.
