Here you may see images of the main characters in the Hollydeva books. They may give you an idea.
But, anyway, it is, of course, much better to read the books and let your own imagination and fantasy let the characters come to live within your imagination!
Just take these as an idea and a help to overview the multitude of characters in these books by Abella Blunk.
Hollydeva,
