Janet,
Encyclopedia Brown, Hardy Boys, Nacy Drew, Sherlock! great stuff. I love the mystery adventure sections too.
Just finished a great adventure book with my son called A Treasure's Trove--beautiful story.
And it's real too, not the mythical creatures part but as well as a great book its also a nation-wide treasure hunt for jewels totaling over 1 million dollars! wild right?
never got past the story experience, but its fun to know there is a hunt for the real jewels as well.
