I'm fighting my way through "Saturn's Child" by Charles Stross, after reading a review that said it was a fine homage to Heinlein's "Friday" (a guilty pleasure). It's a little TOO 'out there' for me. I keep thinking of Nancy Pearl's advice; If you’re fifty years old or younger, give every book about fifty pages before you decide to commit yourself to reading it, or give up. Over fifty? Subtract your age from 100 and use that as your guide. For what it's worth, I got to page 89 last night.
