I would choose Hermione from Harry Potter, I like how dedicated she was in her school work and how she loved her friends, Harry and Ron.
So I don´t really have a favorite book, but I would probbably pick a charakter of the riodanverse. I really like Rachel Dare for example. She just has that clear sight to all the things that are happening to the demigods but still isn´t really a part of it which is a very unique point of view I think. I also kind of liked Hazel because she seems to stay calm in ervery situation and carrying about her friends so much, but if I was in her position I defintly didn´t survive.
I'd be Pippin in Lord of the Rings, because he is courageous and homey at the same time. Also he gets to ride an ent.
Ivy from Slouch Witch! Lazy genius.
