Winterkeep recap

Two Monsean envoys drown when their ship sinks in Winterkeep's bay, and Queen Bitterblue refuses to accept it as an accident: they had been investigating zilfium, the fuel at the centre of Winterkeep's politics. She sails there with Giddon and her half-sister and spy Hava, and gets nothing but polite obstruction. Meanwhile Lovisa Cavenda, a student and the daughter of two of Winterkeep's most powerful politicians, starts noticing what her parents are hiding at the family's northern estate. Bitterblue's boat goes down in the bay and she is presumed dead; she is in fact alive, taken and held prisoner in the north, while Giddon and Hava grieve and keep digging. Lovisa uncovers the truth - that her father arranged the envoys' deaths to protect a secret weapon project, with her mother implicated - and it is Lovisa who finds and frees the queen. The Cavendas' power collapses, Lovisa is left to raise her younger brothers on her own terms, and Bitterblue and Giddon return to Monsea together, no longer pretending about each other.

Previously: Bitterblue became queen of Monsea at ten, after her father King Leck, whose Grace let him make anyone believe anything he said, was killed at the end of a thirty-five-year reign of hidden atrocities. As a young woman she uncovered what he had actually done, discovered that her own advisers had been his instruments, and set her kingdom to collecting and telling its true history instead of burying it. She learned in the process that she has a half-sister, Hava, Leck's other daughter, who is Graced with hiding herself and now works as her spy. Her allies include Giddon of the Council, the organisation that works against bad kings across the seven kingdoms. The seven kingdoms have also stopped being the whole world: a route east opened to the Dells, and Monsea now trades across the sea with the continent of Torla, whose leading nation, Winterkeep, is a democracy far ahead of the seven kingdoms technologically. This book opens years later, with Monsean envoys stationed there.

A Monsean ship goes down in the bay off Winterkeep's capital, drowning two of Queen Bitterblue's envoys, and an enormous, solitary creature on the sea floor watches the wreck settle into the trove of sunken things it has been guarding for centuries. In Monsea, Bitterblue refuses the official account. Her envoys had been asking questions about zilfium, the fuel that dominates Winterkeep's politics, and had written home about something they had found. She sails for Winterkeep with Giddon and her half-sister Hava, whose Grace lets her go about unnoticed. In Winterkeep itself, Lovisa Cavenda, an academy student and the daughter of two of the country's most powerful politicians, is watching the guests who come and go from her family's houses and beginning to understand that she does not know what her parents are doing.

Winterkeep is a democracy split between two parties: Scholars, who argue that zilfium should stay in the ground, and Industrialists, who want it burned to power a modern nation. Lovisa's mother Ferla is a Scholar of considerable power and her father Benni is an Industrialist, and the household is a political instrument as much as a family. Bitterblue's questions in the capital get courtesy and no facts, and she chafes at being handled; she and Giddon grow closer as the delegation gets nowhere. The country is stranger than Monsea's envoys reported: blue foxes bond to human households and touch their minds, and telepathic sea creatures called silbercows carry pictures of what they have seen to anyone who will swim out and listen - including pictures of a ship going down. Lovisa's uncle Katu has gone missing on his travels, and her father's northern estate is receiving visitors it should not be receiving.

Bitterblue is lost on the water. Her boat goes down in the bay and everyone, Giddon and Hava included, believes the queen of Monsea has drowned exactly as her envoys did. She has not: she is alive, taken out of the water by people who wanted her gone, and held prisoner far to the north where nobody will look for her. In the capital, Giddon and Hava grieve and go on working the diplomatic and criminal trail, now with a dead monarch on their hands and a delegation that cannot say what it suspects. Lovisa, following her own family rather than the politics, gets close enough to the northern house to see that whatever her father is protecting there is worth killing foreign envoys over, and close enough for it to cost her the safety of being an obedient daughter.

Lovisa assembles it: the Monsean envoys were murdered because they had learned that her father was secretly funding work toward a zilfium weapon, and her mother's hands are not clean either. She is now the only person in a position to prove it, acting against both her parents, with three young brothers to think about and no adult ally she can safely rely on. Bitterblue, still held and still believed drowned, has worked out roughly the same thing from the other end, and has to keep herself alive long enough for it to matter. Giddon and Hava, meanwhile, are pursuing the same trail in the capital in the belief that they are avenging a dead queen rather than looking for a living one.

Bitterblue is found alive and freed, and Lovisa is the one who does it, acting on what she has learned about her own family. The Cavendas' scheme is exposed and their power destroyed. Lovisa comes out of it responsible for her younger brothers and, for the first time, out from under her mother, choosing a life she picks rather than one arranged for her. Bitterblue, alive after being mourned, ends the diplomatic pretence with Winterkeep and prepares to take Monsea home a much clearer picture of what an industrial power will do to protect a weapon. She and Giddon, each of whom spent part of the book believing the other lost, stop pretending about each other and are together openly. Winterkeep's own argument over whether to burn zilfium is unresolved and now considerably more dangerous, and the creature on the floor of the bay keeps its hoard, its solitude, and the secrets that the silbercows and the bonded foxes have been keeping from the humans they live among.

The envoys' deaths were murder, arranged to protect a secret zilfium project, and the plot ran through the Cavenda family. Lovisa is the one who assembles the proof and acts on it, against both her parents, and it costs her the household she grew up in: the family's power collapses, and she is left responsible for her three younger brothers and free of her mother for the first time. Bitterblue, given up for drowned by everyone including Giddon and Hava, is alive, and is found and got free. Her reappearance ends the diplomatic fiction that Monsea was being told the truth about anything in Winterkeep. Bitterblue and Giddon, each having spent part of the book believing the other lost, stop pretending about what they are to each other and end the book together, openly. Bitterblue sails home to Monsea with Giddon, Hava and the knowledge of what Winterkeep's industrial politics is capable of, and Winterkeep's argument about whether to burn zilfium at all is left unresolved and now far more dangerous. The great creature at the bottom of the bay, and the fact that both the silbercows and the bonded foxes have long known things about their humans that their humans do not know about them, remain part of the world the story leaves open.
