On swift horses

Summary: "Muriel is newly married and restless, transplanted from her rural Kansas hometown to life in a dusty bungalow in San Diego. The air is rich with the tang of salt and citrus, but the limits of her new life seem to be closing in: She misses her freethinking mother, dead before Muriel's nineteenth birthday, and her sly, itinerant brother-in-law, Julius, who made the world feel bigger than she had imagined. And so she begins slipping off to the Del Mar racetrack to bet and eavesdrop, learning the language of horses and risk. Meanwhile, Julius is testing his fate in Las Vegas, working at a local casino where tourists watch atomic tests from the roof, and falling in love with Henry, a young card cheat. When Henry is eventually discovered and run out of town, Julius takes off to search for him in the plazas and dives of Tijuana, trading one city of dangerous illusions and indiscretions for another." --
