"Oddly enough, I first read Thunderball and a few other James Bonds when I was 10. Do you think he was the Harry Potter of our generation?"
Dammit, yes! Why didn't I think of that? Potter may be children's fiction openly read by adults, while Bond was adult fiction read (often to adult disapproval) by children, but the generational crossover and the enormous cultural wave feel very much the same.
Although, Gail, you're far too young to be speaking of "our generation"...
