For Harry Turtledove (known to me mainly as H.N. Turteltaub) fans, a blog and a new alternative history novel:
Winter of Our Discontent: The Impeachment & Trial of John F. Kennedy, Written by Harry Turtledove & Bryce Zabel or: What if John Kennedy survived Dallas?
Mr. Turtledove holds a Ph.D. in Byzantine History, and according to Wikipedia (obviosuly approved by Turtledove as it's linked from his blog), as H.N. Turteltaub he not only wrote the Byzantine novel Justinian – about the 7th century Justinian – which at one time we discussed in our reading group, but also this 4th century BC Hellenistic Traders Series set shortly after the death of Alexander the Great:
Over the Wine-Dark Sea (2001)
The Gryphon's Skull (2002)
The Sacred Land (2003)
Owls to Athens (2004)
If anyone has read these books, I'd appreciate a comment.
