"It's not true," says a character in Jane Smiley's funny, passionate, and brilliant new novel of horse racing, "that anything can happen at the racetrack," but many astonishing and affecting things do -- and in Horse Heaven, we find them woven into a marvelous tapestry of joy and love, chicanery, folly, greed, and derring-do. Haunting, exquisite Rosalind Maybrick, wife of a billionaire owner, one day can't quite decide what it is she wants, and discovers too late that her whole life is transformed . . . Twenty-year-old Tiffany Morse, stuck in her job at Wal-Mart, prays, "Please make something happen here . . . This time, I mean it," and something does . . . Farley, a good trainer in a bad slump; Buddy, a ruthless trainer who can't seem to lose even though he knows that his personal salvation depends upon it; Roberto, an apprentice jockey who has "the hands" but is growing too big for his dream career with every passing day; Leo the gambler and his earnest son, Jesse, who understands everything about his father's "system" except why it doesn't work; Elizabeth, the sixty-two-year-old theorist of sex and animal communication, and her best friend, Joy, the mare manager at the ranch at the center of the universe--all are woven together by the horses that pass among them: two colts and two fillies who begin with the promise of talent and breeding, and now might or might not achieve stardom. There are the geldings -- Justa Bob, the plain brown horse who always wins by a nose, a lovable claimer who passes from owner to owner on a heart-wrenching journey down from the winner's circle; and the beautiful Mr. T., raced in France and rescued in Texas, who is discovered to have some unusualand amazing talents. And then there is the Jack Russell terrier, Eileen, a dog with real convictions -- and the will to implement them. The strange, compelling, sparkling, and mysterious universe of horse racing that has fascinated generations of punters and robber barons, horse-lovers and wits, has never before been depicted with such verve and originality, such tenderness, such clarity, and, above all, such sheer exuberance.
