The Cross, the final book of Kristin Lavransdatter, begins after Kristin’s husband Erlend Nikulaussön’s political intrigue has resulted in the loss of all his property to the crown. Kristin and her family have resettled on her farm, Jörundgaard, which she inherited from her father. Erlend is no farmer, however, so Kristin and Ulf Haldorssön must see to everything. Kristin despairs because her sons are not learning how to keep the estate. Instead, they go running off with Erlend to hunt and occupy themselves as knights do. The likelihood of their being able to lead a knightly life is little, though, because of Erlend’s disgrace.
Although Kristin believes that her relationship with her sister, Ramborg, and brother-in-law Simon Andressön is good—in fact, she turns to Simon when she needs help—she finds that Ramborg is jealous of her.
This novel is the last volume of the series, and I found it more touching in several places than I did the other two. Kristin has found that her headstrong insistence on marrying Erlend has brought her to a life of unending care, and she must somehow resolve this.
This is a really interesting series which endeavors to show the whole of this medieval woman’s life.
What? Me Read? 
This is a book I’d like to add to my club list.
It’s the last of a trilogy, so you should add all three. They are all good.
