The League of Gentlewomen Witches
Charlotte Pettifer is the prophesied future leader of the Wicken League. Witches, if such a thing existed (which, clearly, don’t) that know how to levitate objects. Charlotte is particularly noted for her skill.
The Wicken League is in opposition to the Wisteria Society, a group of miscreant pirate women known for plundering society, and each other.
Alex, a rogue pirate, is intent on getting his hands on the long-lost amulet of Beryl Black. And so, too, are the members of the Wisteria Society and Wicken League, including Charlotte.
Kidnapping silliness ensues (although who kidnaps whom is hotly debated).
Great book with plenty of puns, action, humor, and adventure.
