Most the Hardy Boys books are the same honestly. They both have to have brain damage for as often as they were knocked out and likely concussed. It's Interesting to see how popular fan fiction has become over the past decade or so.
Yeah, I can imagine that. My mom used to read Nancy Drew and she said every single book was exactly the same too.
Somehow I missed that series too. One series I do remember that I was obsessed with was the Choose Your Own Adventure books. I loved those things. I ended up jumping from those right to things like Sherlock Holmes in jr high, so I missed a lot of the regular early teen books.
Choose your own adventure were cool. Tom Swift was cool because it covered so many eras and it was pretty mild science fiction too, so not really heavy.
