Last week, since I enjoyed Fatherland so much, I read three more books by Robert Harris.
Archangel is a modern thriller centered around the hunt for the lost diary of Joseph Stalin.
Enigma is a fictitious look at Bletchley Park's codebreaking efforts during WWII.
And finally, Pompeii is a great historical novel set in the four days leading up to the eruption of Vesuvius, filled with fascinating technical information on the Roman Aquaducts.
I'm currently reading Every Dead Thing by John Connolly, a spiritual crime thriller. More information on that when I've finished.
