Moondance in Red (Moondance Trilogy #1)
Salem Archer

Gorgeous and arrogant billionaire MASON REID has no trouble getting women and no desire to keep them. Thanks to a hard lesson learned from one vicious little gold-digger, he hasn’t had a meaningful relationship in two years. With no way to be sure if women want him or the money, he’s content with an easy routine of one-night-stands—that is, until he meets Maggie Dupree.
Neither can deny the intense attraction at their chance meeting, and once Mason becomes the target of Maggie’s spirited foul-mouthed rant, all bets are off. He concludes two things: one, he must have her and two, he doesn’t want her to know about his money.
