Charlotte Wilmont, a confirmed spinster, loves her best friend's brother, Sebastian Marlowe. He barely knows she exists until fate takes a hand. Charlotte inherits a magical ring. She awakens to find herself in Sebastian's arms, not as his wife but as his mistress. Shy Charlotte is transformed into cheeky Lottie Townsend, a Cyprian adored by all. Charlotte has gained her heart's desire, but it comes with a hefty price. Her previous life does not exist and the people she knew have endured many hardships. One of the biggest changes is that practical Sebastian is now a devilish rake.

Sebastian Marlowe, Viscount Trent, awakens one morning in his exquisite and enchanting mistress' bed. Gone is the dull practical man prepared to marry an heiress to ease his family's debt. Yes, he will eventually marry, but now he needs to spend time with the minx who's stolen his heart. Ignoring his family's dire straits, Sebastian concentrates his limited funds on the woman he loves but cannot marry.

Charlotte realizes she must turn back the clock, for loving her will destroy Sebastian and his family. If fate does reverse time, will Charlotte be able to recapture Sebastian's attention and love as herself and not Lottie?
