CASH McCALL (444 pp.)Cameron HawleyHoughfon Mifflin ($3.95).
THE GIANT'S HOUSE (437 pp.)Frederick LaingDial ($3.95).
These two novels seesaw between a love of business and the business of love, and both writers make big business a good deal more fascinating than love.
Cameron Hawley (Executive Suite) has fashioned the better book around an up-to-the-minute brand of millionaire. Cash McCall is a jut-jawed dynamo who buys depressed companies cheap, jacks them up into profitable operation and sells them dear. Men who do not know him hate him and call him nasty names, e.g., "operator," "raider," "wrecker."
