In a twist on the classic fairy tale, a princess in fifteenth century Spain refused to wait to be rescued by a prince but instead chose one for herself. Even then, she would not marry him until they’d reached an agreement that was revolutionary for her time—their marriage would be an equal partnership captured in the motto: To stand as high, as high to stand, Isabella and Ferdinand. This book tells the real and remarkable story of the princess, Isabella of Castile. The partnership that she made with her prince was a happy and successful one. Without her, both Spain and America would not exist as we know them.

Richly illustrated and narrated with humor, The Thinking Girl’s Treasury of Real Princesses brings to life the stories of real and remarkable princesses who managed to do what few thought possible.
