Under Sea, Sun and Sails offers a richly laden narrative gleaned from archived letters, unpublished memoirs and ships records that also contextualizes their challenges in the unique era of American history between 1851 - 1861.  This intimate account lends an uncommon truth to the story of Joseph and Malvinas Marshall, a ship’s captain and his wife who became partners in the whaling industry while devoting themselves to each other as they sailed the world’s oceans in search of whales.
