Start with The bridal wreath, the first volume of Kristin Lavransdatter. It is the obvious answer and it is also the right one: Undset won the Nobel Prize in 1928 principally for this trilogy, and everything else she wrote reads differently once you have it. The alternative people reach for is Gunnar's daughter, because it is short and medieval and looks like a gentle way in. It is not really a way in at all — it is a hard, compressed saga pastiche from 1909, written before she had found the method that makes the trilogy work, and starting there tends to give people the wrong idea of what she does.
Before you order anything, though, deal with the practical question, because it will affect eleven hundred pages of your life.
Which translation you are buying
Kristin Lavransdatter exists in English in two competing versions, and they read like different books. The older translation, by Charles Archer and J. S. Scott in the 1920s, renders Undset's plain modern Norwegian in a deliberately archaic English — thou, wouldst, ere — on the theory that a medieval setting wanted medieval-sounding prose. It also quietly trims some of the sexual content. That translation is the one whose volume titles are The bridal wreath, The Mistress of Husaby and The cross, which is what our catalogue holds.
Tiina Nunnally's translation, published by Penguin between 1997 and 2000, uses ordinary contemporary English, restores the cut passages, and won a PEN translation prize. Its volumes are titled The Wreath, The Wife and The Cross, and it is also sold as a single fat paperback. Most readers now prefer it, and if you are new to Undset it is the easier road; the Archer and Scott version has its defenders, who argue the archaism suits the material. What you should not do is start one and switch midway, because the naming and register shift under you.
The trilogy, in order
There is no controversy about the sequence. The bridal wreath covers Kristin's childhood, her betrothal, and her ruinous choice of Erlend. The Mistress of Husaby is the long middle: marriage, seven sons, an estate mismanaged, politics that go badly. The cross is the reckoning. The middle volume is where readers stall — it is the least eventful and the most concerned with the grinding administration of a household — and it is also the one that makes the third book land. Push through it.
What comes next, and what you are actually buying
The master of Hestviken is the other great cycle, written between 1925 and 1927 and set two centuries earlier. Our catalogue holds it as a single omnibus of roughly 994 pages containing all four volumes — The Axe, The Snake Pit, In the Wilderness and The Son Avenger — so this is one purchase, not four, and it is a physically heavy object. A newer translation by Nunnally is published separately under the hero's name, Olav Audunssøn, in four slim volumes, if you would rather pay in instalments.
Be warned that it is a harder book than Kristin Lavransdatter. It is slower, bleaker, and far more preoccupied with guilt and confession as theological problems rather than dramatic ones. Plenty of readers who love the trilogy find Olav a wall. If you are unsure, read the first hundred pages before committing to all four volumes.
The short early novels
Jenny, from 1911, is the contemporary novel that made her name in Norway — a young Norwegian painter in Rome, and a study of a woman's independence collapsing under its own terms. It is nothing like the medieval work and is the best single answer to anyone who thinks Undset only wrote historical fiction. Gunnar's daughter is the saga experiment, about 150 pages, violent and stripped bare; read it last, as an origin story for the style.
Where to stop
Most readers should stop after The cross. The trilogy is complete, it is the achievement, and nothing else is required. Read Jenny if you want to see the other half of her range, and take on The master of Hestviken only if the medieval world was the part you did not want to leave.
