Gone with the Windsors - Laurie Graham

When Maybell Brumby, frisky, wealthy, and recently widowed, quits Baltimore and arrives in London, she finds that her old school chum, Bessie Wallis Warfield, is there ahead of her. Impoverished and ambitious as ever, Wallis is on the make. Hampered by plodding husband number two, but armed with terrific bone structure and a few erotic tricks picked up in China, Wallis sets her sights on the most eligible bachelor in the world: the Prince of Wales, heir to the throne. Maybell, with her deep pockets, makes the perfect ally, and her disarming dimness makes her the most delicious chronicler of the scandal that rocked a monarchy and changed the course of history.
