Wicked All Day

Description for WICKED ALL DAY by Liz Carlyle:

Miss Zoe 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, Zoe has accepted -- no, embraced -- her role as society's most incomparable flirt and mischief maker...until in one reckless, vulnerable moment, her future is shattered.

Stuart Rowland, the brooding Marquess of Mercer, has been part of Zoe's extended family since she was a child. As dark and cynical as Zoe is lively, Mercer has always known they would be the worst possible match...until his scapegrace brother Robert does the unthinkable, and winds up betrothed to Zoe. Now, secluded on Mercer's vast estate to escape a looming scandal and the ton's prying eyes, Zoe and Mercer may find that a dark obsession has become a tempestuous passion that can no longer be denied....
