The Sea of Trolls by Nancy Farmer

I finished The Sea of Trolls by Nancy Farmer last night. This book is written more towards young adults (is that what the literaary world calls raging hormonal teens?) but I liked it alot. The book is heavy with Norse 'mythology' and in the appendix, a little bit of history. The end did not leave me asking when the sequel will be available. I like it when a book exists by itself (yes even when it is part of a series). I've handed it to hubby to read and will report his thoughts on if it is written historically accurate, but from what I know, it correctly shows some of how Vikings lived.
