This week, as part of the continuing global commemorations of the First World War, World Book Club is in sombre mood with another timely chance to hear multi-award-winning British writer Pat Barker. She talks about her internationally renowned novel Regeneration, the first in the trilogy of novels which culminated in the Booker Prize winner The Ghost Road. Also shortlisted for the Booker Prize and now recognised twenty-two years after its publication as a modern war classic, Regeneration is a part historical, part fictional exploration of how the traumas of the so-called Great War brutalised a generation of young men.
