*Lost Trails, Lost Cities* is Colonel Percy Harrison Fawcett's memoir of his own exploration and border surveying work in South America. Compiled from letters and journals by his son Brian after Fawcett's untimely disappearance during a journey to find what he dubbed "The Lost City of Z", the book chronicles the waning of the rubber boom and atrocities committed by European colonists and natives alike. Fantastically written with a remarkably unbiased eye, it is not a tale for the unadventurous. In following its pages, the reader is transported to a fantastic and unsettling place that inspired Arthur Conan Doyle's everlasting classic *The Lost World* and countless other stories. But incredible and implausible as it may seem, this story's most impressive aspect is that it is not a work a fiction; but rather a insightful glimpse at a time that once was.
