Madaling - Always dazzling, never ordinary - by Dan DeSantis

Meet the mysterious, very rich and many times married Madaling. No one seems to know her backstory, but everyone wants to know her. Close friend of Cairo Pemberton, the ladies find intrigue and adventure while dashing through the mad world of fashion and society. Madaling never dresses down, so dress her up for everything! Her friends call her "The Sphinx." Behind those jeweled eyes is a mind always watching, always thinking. Is she seeking husband number five or stirring up a new business venture . . . or just plain stirring up trouble? Her face, her figure, her magnificent wardrobe all belie the fact that when push comes to shove, we have a woman who doesn't mind getting her beautifully manicured hands dirty.
