Re: Children's Story Books featuring female captains?
Swallows and Amazons is great - but keep in mind that it was written in the first half of the century in england. It contains some antiquated perspectives on British imperialism that might be difficult to explain to kids.
I bought it for my own 7yr old daughter, remembering only that I loved the books when I was a kid. Next thing I know I have to explain why the kids in the book are pretending to be the first white people to visit an island, what they mean by pretending that the island was full of dark, black, natives, etc...
