Oh I forgot my favorite:
The Pirate Queen by emily arnold mccully, its out of print but mass produced so pretty cheap online used. This book is a little older but i read it to my ds anyway. Its about a the Irish pirate Grace Omallys life. Its great it features her as a kid, fighting, marrying for property aquisition, general pirating, and meeting the queen of england! Kinda sucks that in the real story she basically sold out to the colonizing queen in exchange for protection of her own lands. But this is made up for by the page where she gives birth and is bfing her baby on the ship, then a battle starts and she puts down her baby and runs up to the deck and whips a blunderbuss out of her cloths!
I also plan to move to pippy longstockings as soon as possible.
