Looking for an old Harlequin from the 90's I think. Her name was Willa or Wilda. She had an Uncle or Grandfather named Poppy. Her husband ran off tired of being married and wanting to drill for oil. The book begins with him returning to find an auction happening at their place and to realize she has had his baby. I remember he lives in a trailer as he tries to win her back. Her hand is crushed at a drill site and he has to help her and tend to her.
