"Born to herd, but hemmed in on a small ranchette in Laramie, Wyoming, Chico, a four-year-old American Quarter Horse, longs for a bigger life amid the vast grassland and big blue sky that lies beyond, just out of reach. When Chico comes to live with Sierra --a teen who yearns to learn the sport of cutting-- on her family's cattle ranch, his zeal and her enthusiasm seem like a perfect fit. But Chico is afraid of cows and instinctively tries to chase them off. Can Sierra, a beginner too, help him learn enough discipline to conquer his fears and instincts, and find his own true self?"--P. [4] of cover.
