A shy spinster magically transforms into her beloved Viscount's seductive mistress in a "witty and sensual historical Regency . . . nothing short of brilliant" (Booklist). When a promised inheritance turns out to be a fraud, shy spinster Charlotte Wilmont makes an impetuous wish that despite her lack of charm and fortune, she could capture the heart of the one man whom she's forever adored-Sebastian, Viscount Trent. With that utterance, Charlotte awakens shocked to find herself intimately entwined with Sebastian. But the respectable man she knew is now a most rakish devil and she is . . . well, by some inexplicable magic, London's most infamous mistress. Being the scandalous Lottie Townsend affords Charlotte unimaginable freedom-passionate nights with Sebastian, endless days of shopping, and adoring fans. But all too soon, Charlotte finds that being a man's mistress isn't the same as being his wife. Yet if she returns to her old, respectable life, can Charlotte trust there will be enough magic left to recapture Sebastian's heart . . . and reawaken his rakish desires?
