Readers who are entranced by sweeping historical sagas will devour Birdsong, Sebastian Faulks" drama set during the first world war. There"s even a little high-toned erotica thrown into the mix to convince the doubtful. The book"s hero, a 20-year-old Englishman named Stephen Wraysford, finds his true love on a trip to Amiens in 1910. Unfortunately, she"s already married, the wife of a wealthy textile baron. Wrayford convinces her to leave a life of passionless comfort to be at his side, but things do not turn out according to plan. Wraysford is haunted by this doomed affair and carries it with him into the trenches of the war. Birdsong derives most of its power from its descriptions of mud and blood, and Wraysford"s attempt to retain a scrap of humanity while surrounded by it. There is a simultaneous description of his present-day granddaughter"s quest to read his diaries, which is designed to give some sense of perspective; this device is only somewhat successful. Nevertheless, Birdsong is a rewarding read, an unflinching war story and a touching romance.
