What is the author's style in War Comes to Willy Freeman by James Collier?

The story is easy to read and the action moves along quickly, holding the interest of the reader throughout the book. From the first moments, Willy is caught up in the war that is nearing her home and threatening her family. The language is also easy to understand with few difficult words, but the delivery could be difficult for some readers. For example, Willy is uneducated and her dialogue is written to exemplify that.
