Jim Newton and his foreman, Pete, spy a jet-black stallion leading a herd of wild horses and determine to tame him. They catch him - but taming him is something else entirely. Meanwhile, orphan Joey Clark is determined to meet Fury, and he sneaks out to Jim's ranch. He develops a bond with Fury - and with Jim, who adopts him. That's just the start of their adventures.
The book is adapted from a bunch of the TV episodes from the Fifties, and Miller does a splendid job of it, too. Some of his writing is very moving, and he clearly knows his horses. An excellent adaptation, and I've already tracked down the rest of the series!
