Edgar Perdue comes from a long line of Edgar Perdue's; every single one of them has lived on the same street on the island of St. Atta for generations. Seemingly separated from the outside world - half by an ocean and half by a cliff called The Crescent - the youngest Edgar dreams of moving away from the island to experience life away from the constraints of his ancestry. When he finds a dead mail love letter in his parent's post office his motive becomes clear - he must find the person to which the letter was addressed and deliver the words that went unsaid.
