What is the main conflict in The Prince of Tides by Pat Conroy?

The Prince of Tides is the tale of the destruction wrought upon the lives of a family through denial, abuse and lies. The story begins with the earliest recollections of Tom Wingo about his mother's love of language and the beauty of the natural world around them. It has profound but different effects on each to the three children - Luke, the eldest, and the twins Tom and Savannah. The children also learn a love of nature from their father, Henry Wingo, a man of unrefined behavior and traditional southern male attitudes.
