This is a young adult saga involving a Viking quest. It has all the heroic quest features with creatures, sidekicks and villains.
This is a book that should play well with the young teen. It is an easy and quick read. The dialogue is not stilted with fake language. The characters are highly flawed and demonstrate normal immaturity. Dane the defiant has to deal with his own personal foibles while becoming a chief protagonist. Demonstrating how rivals can become friends is a positive aspect of the book. Astrid is a great role model for young women, demonstrating that women do not have to be victims. She shows that women can be skilled and frightening as warriors. (Anyone who is married should already realize that but keep in mind the book is written for kids.)
The authors did a nice job showing courage, cooperation, conflict resolution while interjecting age appropriate humor.
I recommend the book .
