Mr. Grew lived in North Dakota as a child, according to the first page of this paperback; this book and others are based on his childhood. I read this while I was probably in junior high school and we had a TAB book monthly program and I liked it enough to save it for all these years. I think Queen is a wild horse who is captured and finally set free to live out her life on the prairie with other horses. There are pen sketches throughout the book, but the illustrator is not listed.
