This is the third book in the series, The Goose Girl by Shannon Hale. Here is my review for the first book and here for the second book.
The first book is told by Princess Anidori/Isi and the second is told by her friend Enna. This third book is about their friend, Razo an animal worker in the Bayern kingdom. Razo has always wanted to be in the King's army, however only City people can, not lowly Forest Borns. So it's a big surprise for Razo when the King asks him to join the army. Nobody respects him as he is not a great fighter like everybody else. Can Razo prove himself? All of his friends are in love, can he find the woman of his dreams? This is a fantastic book for anybody who loves fantasy books! I give it a nine out of ten!
