Nimona by Noelle Stevenson is a favorite of mine, kind of a weird fantasy/superhero riff that has some rather dark elements, but is generally funny and sweet.
Through the Woods by Emily Carrol is darker, a collection of some excellent, short scary stories (most structured like fairy tales) in comics form. If your daughter likes horror at all, I strongly recommend her work, she is very good. His Face All Red is collected in the book, and is a good introduction to her work.
