A rich and powerful family, struck by tragedy, gathers in a lawyer's office to hear the announcements of their late father's will. Of the five candidates in the room, it seems perfectly obvious who will inherit the company and be named the sole successor of a substantial fortune. But instead of cheques, the potential heirs are each given envelopes. Instead of the keys to an empire, they are handed cryptic clues pertaining to a bizarre and twisted treasure hunt, designed by their father to test them. This trial of brotherhood and sisterhood will likely end in bloodshed. Travis Madden, a mathematical prodigy, did not expect to find himself caught up in a rat-race, but his expertise in codes and number patterns makes him the unlikely key to finding a dead man's lost fortune. Driven by the need to protect a young heiress from her murderous family, Travis must follow the clues and solve the puzzles before this dangerous game of greed and power consumes them all. There can only be one successor.
