Book seven in the Brotherband Chronicles series. Another great adventure for The Herons! I have gotten firmly attached to each member of this group of the course of the last six books. I now know more about sailing then I ever did before but Flanagan has a way of teaching you without making it feel like a lesson which is nice. A man from Stig's past pops up and needs the crews help retrieving the kidnapped son of the Empress of his adopted kingdom. Of course they have to help and things just get really exciting from there as they go about rescuing the victim. This book is perfect for kids in grades 4-6. The vocabulary is hard enough to be challenging while the story is fast paced enough to really keep the readers interest. Highly recommended for fans of children's middle grade fantasy novels and ships of course. I really enjoyed it so I give it 4/5 stars.
