I’m reading an article about character development in writing stories for middle grade readers (MG) and young adult (YA). Some writers have asked how they can make their main characters more three-dimensional. A good way is to put the character’s name at the top of a page, then list attributes that are physical (hair color, eye color, tall, etc). Then list what fears she might have, what she likes about herself, dislikes about herself, favorite foods, etc. You might not be using all of these in the story, but it helps the writer visualize the character and how she might act or react in a situation.
Currently I’m in the middle of rewriting an MG novel, trying to make the main character more “real.”
