The Ultimate Millionaire (The Million Dollar Catch #3)

Todd Aston III's reputation as a playboy preceded him; he wore power as seamlessly as he wore his custom-cut suits. But Marina Nelson had promised her sister who was marrying Todd's cousin that she'd help him plan the perfect wedding. And somehow, between tasting cakes and modeling wedding dresses, Marina discovered that she wanted Todd and that Todd wanted her. She was powerless to prevent the inevitable. Yet the harder she fell for Todd, the more she realized that he didn't trust marriage-minded women.
Which made her grandmother's offer of a million dollars to whichever Nelson sister married him a big problem.
