"Sara Alton was in love with Michael Fenton, the aspiring young playwright. But she lost Michael to the beautiful, honey-haired actress, Ursula Manning, when his first play was produced. Fighting her unhappiness she sought success as a dress designer, because she thought it would put her on an equal footing with Michael and perhaps bring him back to her. And she found Tom Grierson, a gruff, unpretentious millionaire whose money gave him the power to run other people's lives very much as he chose, ready to set her up in an exclusive shop of her own. She would be Sara Alton, Inc. - but what must she risk, what would failure mean? Tom Grierson put it up to her as a gamble, and Sara accepted the bargain with determined daring. How Sara plunges into her venture and faces all its complications makes a beguiling story. When she finds herself feeling actually glad to see the "villain" of her tale, she may well wonder what is going to happen. Challenge to Happiness is one of the gayest romances Maysie Greig has ever written." (from frontmatter, Doubleday 1937)
