I bought my grandson the entire set for Christmas. I was trying, trying, trying to remember the author's name on the front of the box but it just wouldn't transfer to my typing fingers.
It's his pen name. He does a lot of ridiculous things like saying that A Series of Unfortunate Events really happened, saying he has a sister named Kit who dies, and a brother named Jacques who dies, and it's all ridiculous, and I stopped reading just because of it.
Carolyn Keene and Franklin W. Dixon are not real people. The Nancy Drew and Hardy Boys series were written by groups of ghost writers who invented those pen names.
also, just a suggestion, maybe you could accept real names in addition to pen names, like Theodor Geisel for instance.
(That was sarcasm, by the way.)
Awesome quiz, though!
