Answer:
An interesting character in the book I read is Ivypool, from the book warrior cats, Omen of the stars. She is interesting because she was strong-willed, a huge risk taker and she was an amazing sister. At the beginning of the book she became a little jealous that her sister was better than her, and was more important than her. She was especially angry when her sister was chosen to go on an important mission when she wasn't. This unmistakably led her to the dark forest where she was trained to kill. But she didn't realize the true intentions of the dark forest so she was made to think that she was helping her clan. She wanted to prove that even she can be just as good as her sister, this is one of the reasons I find her interesting, I also find her relatable because sometimes we have all experienced this in our lives. So now she thought that she was just as good and important as her sister but in reality she made a grave mistake which started a conflict between her clan; thunderclan and shadowclan. This was when Ivypool realized the true intentions of the dark forest, after her sister found about this. And instead of stopping her training, she vowed to spy on the dark forest to learn their secrets, that would later on help the clans, in the final battle, when one of her clanmates from the dark forest found out about this, he attempted to kill Ivypool, but was saved by Hollyleaf, one of her clanmate, who dies because of this. I found her overall character intersting because she risked her life to save the clans later on.
Something that surprised me, was that after she found out about the ill intentions of the dark forest, she realized where her loyalties lied, and fought with the clans
