Excited to explore the secrets of wine country, Brooklyn attends an excavation of the caves hidden deep under her parents' commune - and the findings are explosive. A room is unearthed, and it contains a treasure trove of artwork, rare books, a chest of jewelry ... and a perfectly mummified body. A closer examination of the murdered man's possessions reveals a valuable first edition of Jules Verne's A Journey to the Center of the Earth. Hidden in the book is a secret map that unveils an even greater hoard of treasures brought to California by French winemakers fleeing the Nazi invasion with the commune leader's grandfather, Anton, among them.
