Sea of Trolls (theme)

Sea of Trolls has many important themes. The brave young Jack did not give up after he and his sister were captured by the berserkers. He tried every possible way to protect his sister and himself under dangerous conditions. He knew he needed to build a strong relationship with his captors. Eventually, he became good friends with his captors, especially Olaf, who was the leader of the berserkers. Jack was also trying to protect Thorgil, a young female berserker. In return, Olaf and Thorgil saved Jack from the attack of the troll-bear and dragon while they were searching for Mimir's Well.

I also learned that we should believe in ourselves. In the beginning, Jack thought that he couldn't do anything. Of course, that caused some of the berserkers to think that he really was useless. However, he proved that he was a very good bard. Eventually, another bard showed him that it was very important to believe in yourself. If you have confidence, you will find a way out, even during a messy or dangerous situation.

We should be optimistic as well. In the beginning, Jack thought that he would be killed. When he decided to try and save himself and his sister, Lucy, things started to get better. He and Lucy successfully returned home.
