Prince of Dreams by Lisa Kleypas

A wealthy and bitter exile, he most dangerous and desirable man in all of England, he burns to possess a proud, headstrong beauty who is promised to another. But winning Emma Stokehurst's exquisite hand through threats and determination does nothing to fill the empty spaces in Nikola's heart—until passion's magic carries the handsome, tormented prince back to a bygone era of splendor and romantic dreams. For there his destiny awaits him in a distant life. And in one remarkable woman's tender touch—achingly familiar but gloriously new—he must seek the elusive promise of ecstasy . . .and learn, at last, to love.
