I was reading the Flemming books through the 60's. I didn't get into Nancy Drew too much, I was a girl/woman from stuff going on at home. I wanted the racier stuff. I read some of the Hardy Boys though. I read all of the horse stories then started in on Hobbit and Sci-Fi.
I started reading at 5. Some one gave us the Oz series and some of the drawings freaked me out so much I tore the pages out. That didn't go well with my mom. :(
I didn't know any of the girls in out clique who read them.
My wife loved the flicks, mostly because of Sean, but wouldn't pick up the book.
