Eileen Power does it better
This book is written in a readable style, and has some interesting information, but I found Eileen Power's "Medieval People" to be both more informative and a more delightful read. This could be something to read AFTER reading Power's book.
However, this book does contain some information about Anglo-Saxon culture which is not addressed by Power, whose historical biogaphies mostly discuss people living after the year 1000.
It's worth reading both books side by side.
