Loved this second in the series. I will not publish my complete review until closer to the book's release date.
But, for anyone who enjoyed the first in this series, the second is even better. The moral themes become clearer, Desi grows as a character, and the action just gets better.
I would recommend this series to any fifth grader through high school. Granted it might be a little "young" for high schoolers, but the story is just adorable.
