Yes, I've read this one before, and blogged about it too, but it's such a good book it's worth writing about again. It's too rare a combination to have a scholar like Piers Vitebsky who can write an engaging book for the general public. Not that this book is unique in that way, but it's unusual.
This really is the book to read if you're going to read something about Siberia. Highly recommended.
And I'm going to link it on Melissa's challenge, because it's just that good.
