I just finished Valhalla Rising and now want to read a non-fiction book on colonizers prior to Columbus. Any recommendations on a scholarly work on this that sums up the research. If not a composite book, then one just on viking explorers would be great.

Welcome to the forum, runner! I'm sure someone on here will have an idea for you. Good luck!
