History / Books about history of Poland in the 20th century. [10]

hello, can you please tell me where I can find God's Playground (the 2nd volume) by Norman Davies in electronic format and free. Or other books about the history of Poland and especially about the WWII period, about the Warsaw Uprising, and about the communist regime in Poland. thanks.

p.s.: and, of course, if you could possibly tell me how to get these books free and in electronic format.

oh, I forgot to mention that I do not speak Polish (I'm not Polish). if you know links for these books translated in English, it would be great. thanks again.
