Exclusively Yours — Joanna Scott

They had once made a promise to belong only to each other, but he was Marc Fremont of the Louisiana Fremonts, and she was only Megan Mahlar, of the nowhere-in-particular Mahlors, and the promise made with the hot impetuosity of youth was destined to be broken.

Older and wiser, they met again. This time they knew that nothing could guarantee their happiness--not his wealth or her lack of it--nothing except each other. Once again they made a promise not to part, but this time the promise would be kept.
