Get any great surprise books for Christmas? [View all]

It's winter break for my boys - they're off from their colleges - and I loved the surprise gifts, history books, with which they surprised me.

One is The Half Has Never Been Told, about how American wealth and its capitalist economic system was generated and sustained through human slavery; the slaves built this country.

The other is The Spy Who Changed the World It's about the nuclear spy/physicist Karl Fuchs, who fed Manhattan Project and British nuclear secrets to the Soviets.

His punishment for his crime - as I told my boys, and they liked the joke - was that he had to live the rest of his life in East Germany.
