Michael Chabon's books are soon to be e-books. (
news report). I discovered his books by first reading the Yiddish Policeman's Union - which is, marvellous - combines humour and social/historic perspectives and commentary in an alternative history/detective novel blend of genres (it is set in Sitka Alaska, but a Sitka that is a large city, populated mainly by Yiddish speaking Jews who were refugees from Israel when it was destroyed).
His Pullitzer Prize winning novel, The Amazing Adventures of Kavalier and Clay is my favourite of his books and one of the best novels I have ever read - about Jews in New York before, during and after WW2, about the early history of comic books, and about so much more than that.
I also really enjoyed Gentlemen of the Road, another 'genre' book - a great adventure story (Rider Haggard style, but better written) set about 1000 AD along the Silk Road, and the Jewish empire of the Khazars.
