 "Loggerheads" interweaves three separate but related stories that take place in different parts of North Carolina. On Mother s Day 1999, Mark, a young drifter with an interest in endangered loggerhead turtles, begins a relationship with motel handyman George. On Mother s Day 2000, Mark s adoptive mother Elizabeth wonders what has become of her estranged son. On Mother s Day 2001, Mark s birth mother Grace quits her job to begin a search for the child she gave up years before-a search that ultimately brings the stories together.
