After thirteen years away, Thomas returns to Tidewater, Virginia to attend the funeral of his grandfather Everett, and reopens a long-running family feud when he suspects his stepfather of stealing and selling a missing family heirloom; a letter from Abraham Lincoln.

Magnum and a group of his treasure hunting friends are held at gunpoint on a cliff top with the one million dollar prize that was the hidden object of a treasure hunt competition, organized to help promote Robin Masters' new novel by using clues from it.
