Deceive not my heart

This is the first of Shirlee Busbee's Louisiana Ladies series and it's a scorcher. The heroine...Leonie Saint-Andre, is the independent and fiesty granddaughter of an old Creole gentleman who is trying to keep the family plantation afloat. The hero...Morgan, the scion of a wealthy Natchez family, doubts that Leonie is after anything but easy money. The crux of the problem...Leonie claims her son is Morgan's and that he married her five years ago. She has come back into Morgan's life demanding her dowry, but Morgan is certain he accepted neither dowry, nor Leonie's hand in marriage. Though Leonie sends desire sparking through Morgan, he can't reconcile who signed his name to the marriage papers Leonie holds or why her son bears such a striking resemblance to Morgan himself.
