Since I already have a book surrounding wizards/witches, let's go with a fairy!
Ember- A young girl with freckles and short hair. She's not popular but strives to be popular. She's a pretty normal girl, though she doesn't have a mother, just a father. She knows who her mum is, but she doesn't see her often. She makes friends with the two, Kimberly and Allie. She is calm and collective.
Now, let's think of the age we want to start out with. Any ideas?
