"Forty years ago I first linked up with Unguentine and we made love on twin-hulled catamarans, sails a-billow, bless the seas . . ." So begins the courtship of a certain Unguentine to the woman we know only as "Mrs. Unguentine," the chronicler of their sad, fantastical tale. For forty years, they sail the seas together, alone on a giant land-covered barge of their own devising. They tend their gardens, raise a child, invent an artificial forest—all the while steering clear of civilization. Log of the S.S. The Mrs Unguentine is a masterpiece of modern domestic life, a comic novel of closeness and difficulty, miscommunication and stubborn resolve. Rarely has a book so perfectly registered the secret solitude of marriage, how shared loneliness can result in a powerful bond.
