This masterpiece by the Nobel Prize-winning Norwegian author, first published in 1927, has never gone out of print. This is the third volume in Undset's trilogy of historical novels recreating a woman's life during the Middle Ages in devoutly Catholic Norway. The books combine scholarly knowledge of the era with keen psychological analysis to produce a vividly realistic picture of the past. In the third installment, Kristin must overcome the loss and devastation of the Black Death.  (NOR17, $16.00)
