"Ten dead men" by David Beresford is without a doubt the best book on the 1981 hunget strike, a must read.
Yes excellent, but I think it's actually "Ten men dead" as far as I can remember.
Tim Pat Coogan wrote a book just before the hunger strike called "On the blanket" also well worth a read, I reckon it gets overshadowed by what happened later with regard to the hungerstrikes, it really shows how bad things were in the maze before the hungerstrikes.

One of the most interesting books I've read was "Celt and Saxon" by Peter Berresford Ellis, starts from the fall/decline of Roman Britain and Subsequent invasion by Angles, saxons and Jutes and the gradual push back of the British celts to Wales, Scotland and Cornwall.
