The Lost City of Z: A Tale of Deadly Obsession in the Amazon

Kottke usually recommends great books, but I’m lukewarm on this one. Not particularly engaging despite the subject matter which should have been riveting: one of the last explorers in the 1920s, heads off into his 5th (?) exploration into the Amazon with his son and his friend to find the large city of Z, supposedly a huge civilization smack dab in the middle of the rainforest.
