This is a good series about strong female leaders throughout history.  This book is a biography of Isabella of Castile.  Other titles in the series include Hatshepsut of Egypt, Artemisia of Caria, Sorghaghtani of Mongolia, Qutlugh Terkan Khatun of Kirman, and Nur Jahan of India.  The illustrations, photographs of actual artifacts, maps, and time lines bring these biographies alive.  The text is easy to read and presented in a logical and clearly written manner.  The featured women were intriguing and powerful with interesting lives, holding the reader’s attention.  I recommend this series for school libraries.
