I first heard extracts from The Junior Officer's Reading Club by Patrick Hennessey on Radio 4's Midweek and it was compelling and urgent. His exchanges with David Hepworth on The Word Podcast was one of the best radio interviews I'd heard in ages. It was all a revealing enough tale of a young man's rites of passage through Sandhurst, and at first I enjoyed it. By the time he got to Afghanistan, it dragged on a bit. It seems harsh to reduce (edit) this young man's tale, as it takes something away from the sacrifice of his fallen comrades, but he seems to have aspirations to write more and he needs to learn. Anyway, here's a review here that says pretty much what I think.
