Fifteen years after the publication of his acclaimed novel Mason’s Retreat, Christopher Tilghman returns to the Mason family and the Chesapeake Bay in The Right-Hand Shore (Farrar, Straus and Giroux, $27.00) . It is 1920, and Edward Mason is making a call the dying owner of the legendary Mason family estate, the Retreat. Edward believes he can charm the old lady, secure the estate and be back in Baltimore by lunchtime. Instead, over the course of a long day, he hears the stories that will forever bind him and his family to the land. Tilghman, director of the Creative Writing Program at the University of Virginia, is also the author of Road of the Heart.
