Novel about medieval life

In the audioconference last week, I mentioned a novel set in medieval Scandanavia. I said it was a painless way to learn about life in medieval times and the way the church impacted just about every aspect of life. The book is Kristin Lavransdatter by Sigrid Undset.

Here's a review of it:
From 500 Great Books by Women; review by Erica Bauermeister
A landmark among historical novels, Kristin Lavransdatter is part of the body of work that won Sigrid Undset the Nobel Prize for 1928. This trilogy of more than one thousand pages follows its title character through her life in fourteenth-century Scandinavia. It is a novel full of big and dramatic happenings: romantic intrigues, political schemes, and spiritual debates. It is also a novel about one woman's life. Sigrid Undset makes us understand Kristin's love for her sons and husband, the feeling of milk in her breasts, and the hard work of living in the fourteenth century. As does any good historical novel, Kristin Lavransdatter immerses us in its time through rich details concerning dress and manners as well as social and historical events. The multitude of character names is confusing at first, but if you stick with it, Sigrid Undset will give you a first-hand experience of another world.
