As a reader what do you expect from a children's fiction writer?

Hi I'm an avid thirteen year old reader. Here are the crucial elements to a good book from my point of view:
Realistic, flawed characters that change over the course of the plot.
An engaging and swift-moving plot, preferably with sci-fi or fantasy themes
Little or no romance
Thrilling, creepy aspects
A educative and unique moral behind the story.

Adventure, can be fantasy but be reasonable
slight or nearly no romance, better to be telling friendship
bring inspiration without intention (children mostly think that those moral story are lame)
