When I was a young, voracious reader, I used to dream of adventures along the Hudson with Trixie Belden, Honey and the Bob Whites - in my dreams I had short curly hair (just like Trixie) and was a bit of a tomboy - well, not much has changed ;)
My absolute favourite book in the 34 books that I read in the series was The Mystery of the Ghostly Galleon (1979) with a genuine glow in the dark disappearing pirate ship!
Don't mind me while I climb the rigging and dream of pirate adventures...
