Son of the Black Stallion — Walter Farley

Black's Blood
When the Black Stallion's arrives from Arabia, young Alec believes his dreams have come true. Satan is everything a horse should be: beautiful, spirited, and intelligent. But veteran trainer Henry sees something disturbing in the colt's stony gaze.

Satan has his father's fire, but he also has a killer's instincts, and he deeply distrusts every living creature. Henry fears he is impossible to tame. But Alec is determined to win the love and confidence of this wild beast. He'll turn Satan into a champion racehorse -- even if it means risking his own life!
