A year later, Matthew is part of the original Forty-Niners, with a claim and no money--yet. But then he overhears a fellow miner discussing odd glyphs found in his mine and Matthew's family instincts kick in. He sets out to see if the glyphs lead to something bigger than all the gold in California and in the process stumbles upon a group of Forty-Niners who will stop at nothing to claim a fortune.

Set during some of the most important moments in American history, the Gates Family Mysteries follow the ancestors of Benjamin Franklin Gates (immortalized by Nicholas Cage) as they search for treasure and strive to clear their family name.
