The Princess in Black and the Perfect Princess Party by Shannon Hale, Dean Hale

My daughter likes these because the princess is a superhero, which she's super into right now. I personally find the stories a little boring because it's the same thing always, she has to find a way to sneak off and not be discovered, then fights a monster that eventually goes back to monster land. She is a very flat character.
