Funke, Cornelia (2007). Igraine the Brave. 212 pages. Grades 3-6.
Igraine, who has always wanted to be a knight, is turning twelve tomorrow! But, before the celebrations begin, a horrible knight from the neighboring kingdom attempts to steal her family's singing books and attack their castle. To make things worse, her parents have accidently turned themselves into pigs while using magic to create a present for Igraine. The only way that Igraine can help protect the castle is to turn her parents back to their human form, which means bringing back a giant's hair for the spell. Now Igraine will have to prove herself as a knight, help her parents, and save the castle! Find out if she can return in time to defend her home and celebrate her birthday.
