I'm rereading East of Eden, since SFGopher just read it, and his older sibling is reading it now, too.
It's a good one. More or less Steinbeck's modern (turn of the last century) retelling of portions of the book of Genesis. I'm no biblical scholar, but I really like this book. Particularly the characters' dissection of the story of Cain and Abel, and their conclusion re "thou mayest." If you haven't read it, I give it two thumbs up. For whatever that's worth.
