1491: New Revelations of the Americas Before Columbus

This is a fantastic exploration of the Americas pre-European intervention, but it is extremely dry. I'm used to historical texts and academic readings but even with interest in the topic and a willingness to power through, I found myself spacing out and having to backtrack a bit. Persevering did reap reward, though, as the ideas explored in this book are worth examining. Well worth the effort, but it does take effort.
