Last Light over Carolina by Mary Alice Monroe

A very good book by one of my favorite authors, Last Light over Carolina is set in South Carolina.  It is the story of the Morrison Family; Bud, Carolina and Lizzy.  Bud and Carolina are about 30 years into their marriage.  Lizzy is a divorced, single mother of a little boy.  They all live together and help each other out.  Bud runs a shrimp boat, Carolina is a housewife, and Lizzy works at the local diner to make ends meet. 

The story of the relationship between Bud and Carolina is told in a series of flashbacks after Bud goes shrimping alone and gets his hand caught in the winch of his boat.   Trapped with no help, he must hope that the townspeople and his wife figure out where he is and that he needs help.  Can they realize that Bud is in trouble and find him in time?
