* She is described as being "small" and "agile" - This suggests she is not tall and has a slender build.
* She is a skilled hunter, having grown up in the wilderness - This implies she might be physically fit and tough.
* She has long, black hair - This is the only specific detail about her appearance mentioned in the book.
The book focuses more on Hattie's personality, skills, and her role in the story rather than her physical appearance. Therefore, we can assume her physical characteristics are secondary to her character development.
If you are interested in a more detailed image of Hattie, you might consider watching the TV series based on the book, which may depict her visually.
