The Forgotten Sisters, by Shannon Hale

This is the third book in a series. The first book was The Princess Academy, which is possibly a perfect middle grade novel! The second, Palace of Stone, was still enjoyable but not as good. This one.....still enjoyable but less good again. The stakes continue to be upped in the books following the original, and the higher the stakes the more it feels too simplistic, what happens. So although this book was very readable, and I liked the new characters who were introduced in this one, I feel very meh about the book as a whole.
