found this in my local library, and it was a great read. For a neuroscientist to be the writer, he is also a good writer. One passage describes as Peary's wife, coming to the artic from New York City on a relief ship, must have seen an Inuit woman with a Inuit child of white skin complexion, and "must have understood. A stoic woman", as the book describes, decided in not saying anything. Very very detailed, it filled the dots in many areas. Would have liked a critical analysis of the 1912 Henson book "A Polar Explorer" in light of the culture during the time it was written, and how it would have been re-written today, since the book publication could only be possible after Peary's review. And would have also mentioned more about the meteorites found and hauled in the 1890's. But still, the amount of detail and effort in stringing it all together is majestic.
