very, very good book, i would recommend it to anyone. what struck me was that it was (at the most basic level) historically accurate. In real history, the great king Olaf Haraldsson captured a great bard named Bersi Skaldtorfuson, called a skald by the northmen. Bersi ended up writing the Saga of Olaf. I was shocked to realize that, besides the trolls, dragons, etc. It was true!!!

My younger sister bought this for my birthday, I read it and I loved it! The northmen were very entertaining, and it was fun to learn about their odd habits. I especially liked Thorgil's personality. She was tough, and she really wanted to be treated like she was a boy.It was also fun to watch how Jack went from being a farmer's wimpy son to being a bard mistaken for a northman. Lucy was a bit of a brat, but she was still sweet all the same. Some parents might find some of the northmen's customs and ideas repulsive, but I think it's harmless, really. I think 8 and up would enjoy and understand this.

I think "The Sea of Trolls" is a pretty good book and can be read by kids 10 on up. It doesnt have any bad words that can effects kids, but they'll probably have an addiction to the book and won't think about anything else.

I CAN'T GET ENOUGH!!!!!!!!!!!!!
