Query: a real disappointment

this book begins with a riveting account of the Central America and its demise; about a quarter of the book. The book then founders miserably in an undiscriminating tide of details and people who turn out to be UNrelated to the recovery attempt! By the time we get to the excavation of the gold, (the very last chapters) i felt as if the book had sunk to the depths of the ocean along with the Central America.i'm a very disappointed that so few books are edited carefully these days. this book holds more potential than it lived up to.
