The third book in the Hoofbeats series focusing on Katie!

Katie knows she has come too far to give up. Taken under the Kylers' wing, she stays close to the Mustang and clings to her dream of finding her uncle. Then a particularly bad river crossing leaves their guide crippled and their group diminished. Knowing that there is strength in numbers, they join forces with a traveling circus troupe, and somehow make it to Fort Laramie.
