To Covet a Lady's Heart(Landon Sisters‪)‬

After a lifetime of rakish behavior, Lord Maxfeld must pretend he's reformed and find a fake wife. And there is nobody more suitable than Lady Phoebe. Trouble is, Phoebe will not agree to a false engagement and leaves Max no option but to blackmail her into agreeing to his scheme.
Phoebe will go to great lengths to avoid anything remotely dishonorable and blackmails Max right back-directly to the altar. Once married, though, Phoebe wants more than just Max's ring-she wants his heart, something he can never give . . .
Contains mature themes.
