Princess Wilma and the Pirate King — J.F. Holmes

In far-away places of time and space, a young princess, of a land that maybe was or wasn't, is called on to save her friends and her mothers' throne. Ten year old Wilma, heir to the thrones of both powerful Northumberland and small Tuscana, splits her time between the two, spending winters with her father and summers with her mother. Shortly after her return to Tuscana, treachery makes her a captive in the hands of the Pirate King, who is intent on destroying Tuscana with the aid of supernatural allies. Wilma, along with her friends Duncan and Chrissa, must find a way to get back home and foil the Pirate King's bloodthirsty plans.
