A history book that follows a bead that was found in a Viking grave in Repton across to asia where it was likely made. The book details bioarcheology involving comparing the makeup of teeth and bones to show whether people in gravesites are migrants where they likely came from. I'd never heard of that before, and found it all very interesting.

I really enjoyed the first section, but as it went I guess by necessity it became less grounded and more full of could haves and might haves.
