Miss Zoë Armstrong is beautiful, charming, rich - and utterly unmarriageable. So, while she may be the ton's most sparkling diamond, her choice of husbands looks more like a list of London's most unsavory fortune hunters. Since a true-love marriage seems impossible, Zoë has accepted - no, embraced - her role as society's most incomparable flirt and mischiefmaker ... until in one reckless, vulnerable moment, her future is shattered.

Now, secluded on Mercer's vast estate to escape a looming scandal and the ton's prying eyes, Zoë and Mercer may find that a dark obsession has become a tempestuous passion that can no longer be denied ...
