Regeneration is the first book in Barker’s Regeneration Trilogy, followed by
The Eye in the Door, which though featuring more fictional elements than its predecessor, continues the relationships between Billy Prior, Siegfried Sassoon, and Dr. Rivers in the midst of a public campaign in England against homosexuality. The trilogy concludes with the award-winning
Ghost Road, which focuses primarily on Prior and Rivers’s relationship.
Regeneration is most easily-described as an anti-war book, making its arguments not through pacifist speeches or preaching, but by demonstrating the horrors that soldiers experience. Other notable books with similar themes are Kurt Vonnegut’s classic
Slaughterhouse-Five, depicting Billy Pilgrim’s World War 2 service and subsequent insanity; Joseph Heller’s satirical World War 2 novel
Catch-22; and Tim O’Brien’s book
The Things They Carried, which offers a fictionalized account of his own horrific experiences in Vietnam as a young man, viewed through the lens of a writer’s mind, much as
Regeneration frames much of its wartime recollections through poetry. Also, Sassoon (both in the novel and in real life) regards Edward Carpenter’s
The Intermediate Sex as a major influence on his understanding of his own sexuality, since the work helped to describe and define homosexuality in the early 20th century, forecasting a hopeful new age of sexual freedom. Both Siegfried Sassoon and Wilfred Owen appear as characters in
Regeneration, and their antiwar poems are thematically aligned with the novel.
