Never Leave Me — Harold Robbins

Robbins' New York is the world of big business and the men and women who make it big. Honor and decency are nothing in a city where respect is measured by the size of your expense account. And it's the city that Brad Rowan, a man on the make, hopes to conquer on his climb to the top, bringing with him the women he loves, uses, and destroys.
Drawing from his own experiences in New York, Robbins vividly portrays our eternal desire for greed, desire, and blind ambition, in this timeless tale of success and struggle in the city that never sleeps.
