Fired from his job at an Indian casino and armed with a dolphin amulet gifted to him by his Noqoto grandfather, student archaeologist Peter Martinez is on a mission to save Rocky Point, California from an oil giant's development plans. But when his exploration of the sacred coastal land leads him to an ancient burial cave in the side of a cliff, a wave knocks him into the water and he wakes up on the beach—more than 300 years in the past.
His Noqoto ancestors have occupied this shore for thousands of years, but in 1786 their experiences with the Spanish have left them wary of strangers. That this outsider who walks into their village and knows so little of their world hints at their destiny is alarming. But when the village leader's son leads Peter into the wilderness to test his character and resolve, the skills taught to Peter by his grandfather wins over the tribe and they begin to listen to his words of warning. Is there anything they can do to prevent the future Peter says is coming? Or can they use his knowledge to save themselves?
