I'm reading The Anglo-Saxons by Marc Morris. It's non-fiction. Morris' books have a good narrative, but they are scholarly works. I haven't gotten very far into The Anglo-Saxons yet, but one bit I greatly enjoyed was the author drawing parallels between Beowulf and Tolkien's Rohirrim, all while discussing the archaeological evidence for feasting halls and the zeitgeist of the people who'd built those halls.
