I haven't read it. The three books listed above and A Clockwork Orange are the only Burgess I've read. The three that made the list are all 'fictional biographies': Nothing Like the Sun is about Shakespeare, A Dead Man in Deptford is about Christopher Marlowe, and Napoleon Symphony is about (surprise, surprise!) Napoleon. I loved them all, but the Marlowe book was the most fun to read--fast-paced plot and lots of intrigue. What is Earthly Powers about?
