I'm not really a big fan of today's fiction, but for those who are, I can recommend "A Fine Balance" by Rohinton Mistry, a story of Parsees and untouchables in Bombay that's a worthy successor to the great novels of the 19th century. Also, just about anything by Robertson Davies, a great Canadian novelist of recent years. Davies had a real talent for creating characters and drawing readers into a world not so different from our own, but more interesting. His work is uneven, but once I picked up one of his books I always wanted to finish, and when I had, I couldn't wait to read the next one.

On Two Wings, Humble Faith and Common Sense at the American Founding by Michael Novak. (ISBN 1-893554-34-1)I enjoyed his presentation and his documentation...lol, and I'm not that big on footnotes.
