I've read most of Eco's books and enjoyed them, and most of Cornwells. I also enjoyed The Archer's Tale, I think I may want to see the move when it comes out (unless I've already missed it), I heard they were making one.
In my "to be read" pile:
The Island Of The Day Before by Umberto Eco
the Grail Quest triology The Archer's Tale, Heretic and Vagabond by Bernard Cornwell
The Good Earth by Pearl S. Buck
Alas, Babylon by Pat Frank
I've read most of Dan Brown's work, found him before he became "famous". His stuff has always made me sit back and think, something I like in a book.
Some of my recent favorites have been:
All the Amy Tan books. I've read them all. I can relate to her books - they are consistently about a Chinese mother who has a cultural gap with her American-born daughter, and the mother recounts the gripping stories of her hard life. So my mom's not Chinese, but boy... can Asian mothers be alike...
