Master Chief Ginetti has recently passed away. He willed his boat, the Undine, and its logs, to his son, Charles Ginetti. Charles is a Silicon Valley icon, who started a GPS company and built it from the ground up. The Chief's will specifies that Charles should go out on the Undine and read the logs.
Sierra Marney is a fourth generation lighthouse keeper. Her family has been tending the Pigeon Point lighthouse since 1872. Sierra is intimately familiar with the legions of wrecks, and the terrible loss of life that has happened at The Point.
Charles decides to sail the Undine from Santa Cruz to San Francisco to see his daughter. But Charles' ambition is greater than his nautical skill. When he wrecks at the lighthouse, perhaps only Sierra will be able to save him.
