Tempting Her Heart — Brenda Williamson

Marigold is used to having money. When her father dies, leaving her penniless, she believes marriage to a wealthy man would correct her situation. Only the fellow she chooses has a poor, yet extremely attractive cousin who distracts her at every turn with his unique charm and searing passion.

Felix doesn't like the con his cousin is pulling on Marigold, except when he figures out she's playing the same game, he sees nothing wrong in pursuing her for fun, until seriously falling for her gets in his way to keep things between them casual.

When the deceptions unravel, Marigold has to decide between her dream or the wealth of love Felix offers.
