Is this historical fiction, or history proper? I've been reading a series of books on the Middle Ages written by Frances and Joseph Gies that is essentially a synthesis of a massive amount of diaries, books, journals, records - pretty much anything written - and then compiled into a narrative of sorts on various medieval topics. I've read ones about living in a castle, a city, and a village, as well as the life of a knight in general. Next up will be marriage and the family, women, a specific family (that left a lot of written records, I assume), and finally the cathedral, forge, and waterwheel (which focuses on medieval technology). Each of these books basically traces the topic and its development/changes throughout the medieval era, but are also quite readable. Fascinating stuff, if you're into it. They've become a favorite duo of mine, and I will likely re-read them again in the near future, once I shorten my "to-read" list some more.
I just finished "Seven Viking Romances", which was an entertaining series of sagas, but these, unlike most, are clearly not based in fact. They have some very obvious fairy tale elements such as people turning into dragons and giant vultures carrying people off to far away lands. But since I'm a big mythology fan too, I don't mind that these are a bit more fantastical. I'm quite enjoying them!
