This is mainly the story of one man's struggle to live in peace and raise a family in post Civil War Texas, but it is also about the unique friendship between a black ex-slave and a white ex-soldier who rounds up and sells mustangs. Free now has a homestead, and he and his wife, Clara, have a small son, and another child on the way. The story is set within the conflict involving the U. S. Army, the buffalo hunters, the Mexican rustlers, and the Kiowa, Comanche and Cheyenne Indians, all of whom have different viewpoints of what the desired outcome is, and the way it should be accomplished.

Real characters from history join the two fictional main characters in the skirmishes, and Kearby lets us see it all from various viewpoints.  Anderson and Scott don't always agree with the U. S. Army, but are committed to upholding the law of the land in trying to outwit the enemy in a way that results in the fewest casualties on both sides.

Ambush at Mustang Canyon is an electrifying, fast-action story that is historically accurate. Written for young adults, it contains enough excitement to interest adult western and history fans. From the first attack on the freighter Britt Johnson, through the battles of Adobe Walls, Lost Valley and Buffalo Wallow, Free and Parks are caught up in the conflict and are in frequent danger of losing their own lives. 

Mike includes a glossary in the back of the book with word, phrase, and name meanings in Kiowa, Cheyenne,   Comanche, and Spanish languages.  There is also a page with author's notes on history and a page of discussion questions to help gain better understanding of the history and theme of the story. Your reluctant reader would enjoy this exciting series.
