Discovering the Sea is the story of Fern, a sixteen-year-old girl, who is home for the summer after completing her first year of boarding school, and intent on exploring the concept of the Covenant of God. Through discussions with friends and family members, Fern learns about the Baha'i concept of the Covenant as an agreement between God and mankind in which God promises never to leave us alone without guidance. Fern discusses the religions of the past, and the ways in which disunity seemed to arise among their followers after the passing of the Prophets and Founders of the religions. With the help of her family members and friends, Fern studies the wills of Baha'u'llah, the Prophet and Founder of the Baha'i Faith, and 'Abdu'l-Baha, the eldest son and appointed successor of Baha'u'llah, and comes to appreciate the unique and significant Covenant made between Baha'u'llah and His followers.
