Light Bringer recap

Presumed dead after the annihilation of his legions on Mercury, Darrow is a castaway working his way home in the company of former enemies, among them Cassius au Bellona and the Rim's Diomedes au Raa. While Virginia fights a losing defensive war for the Core and refuses to trade the Republic for a dictatorship, and Lyria hunts for the missing Obsidian Volga, Lysander au Lune converts the prestige of his Mercury victory into real power among the Golds. Lysander runs Darrow's company down and kills Cassius, the man who raised him, and afterward stops pretending to be the restrained one. Darrow survives, goes north into the ice to the Obsidian strongholds, and wins an army on their terms; by the end he is reunited with Sevro and back in the war with a force and a purpose again. Lysander closes the book as the ascendant power of the Gold cause and a far worse enemy than the Republic expected, with the final war still ahead of both of them.

Previously: Darrow, born a Red miner on Mars, was surgically remade as a Gold and spent years as a hidden agent before his rebellion broke the color caste, killed the Sovereign Octavia au Lune, and put Virginia au Augustus at the head of a new Solar Republic. A decade later the war had not ended. Darrow defied his own Senate to carry the fight to the Society's remnant, and in the previous book he was cut off on Mercury when the Gold armada of Atalantia au Grimmus destroyed the fleet that had brought him. His Free Legions fought a long and increasingly brutal guerrilla war and were finally annihilated; Mercury fell, and Darrow survived alone, separated from Sevro and from everyone else. On Luna, the Republic was dismantled from inside by a campaign of terror engineered by the Rim's Fear Knight, Atlas au Raa, alongside a populist revolt, a criminal Syndicate and an Obsidian rising; the Senate was gutted and Virginia was left governing wreckage. Ephraim ti Horn died freeing the abducted children, Pax and Electra; the Obsidian Volga disappeared, and Lyria survived. Lysander au Lune, once a hostage of the Rim, came out of the Mercury campaign as the Gold cause's most compelling figure. This book opens with Darrow a castaway, presumed dead, trying to get home.

Darrow is alive and nobody who matters knows it. Adrift and without resources after Mercury, he is traveling under a false face in company he would never have chosen, among them Cassius au Bellona and the Rim's Storm Knight, Diomedes au Raa, and the three of them are trying to work their way back toward the Republic without being recognized, sold or killed. Poverty, disguise and the need to stay invisible push Darrow into places and expedients far beneath the Reaper's legend, including a fighting pit that trades on other people's blood. Meanwhile Lysander au Lune, the hero of the Gold victory at Mercury, is being feted by the Society's survivors, learning how their politics work and how far his new prestige will carry him. His view of himself as a servant of order rather than of ambition survives contact with that world, at least for now.

Darrow's company works its way inward, and its number grows to include the Gold warlord Apollonius au Valii-Rath, a man whose usefulness is exactly proportional to how closely he is watched. On Luna, Virginia au Augustus holds a Republic that has lost its army, its expeditionary fleet and much of its government, with her son Pax returned to her and the Senate a shadow of itself. She has to prepare a defense of the Core against an enemy that badly outnumbers her, while her own allies press for emergency powers and a single hand on the war. Lyria, free of Luna and out of the Republic's reach, sets out after Volga, the Obsidian woman who vanished on the night the children were freed and who is wanted for it. Lysander is drawn deeper into Atalantia's campaign, and into the question of who is using whom.

The Gold offensive reaches the Core, and the war becomes a matter of fleets and worlds rather than raids. Virginia commands the Republic's defense through a long and costly campaign, spending ships and people she cannot replace to buy time and space, while Lysander fights on the other side and builds a reputation that is starting to rival Atalantia's own. Neither side can finish the other outright, and the fighting gives way to negotiation: Virginia and Lysander meet directly, each takes the measure of the other, and nothing is settled. Lyria's search carries her further from anything she knows. Darrow, still presumed dead, is closing on a war he does not yet know how he will rejoin.

Darrow re-enters the war, and the fact of his survival changes its shape: to the Republic he is a resurrection, to the Golds a problem they thought solved, and to Lysander a personal reckoning. His makeshift company, Cassius and Diomedes and Apollonius and the few others who have thrown in with him, is far too small for what he intends, and he begins looking for the only force within reach that could matter, the Obsidians, whose queen is dead and whose loyalty nobody has yet claimed. Lysander moves against Darrow directly, and the pursuit brings both of them and everyone traveling with them into the same fight.

The confrontation between Lysander's forces and Darrow's company ends in disaster. Cassius au Bellona is killed by Lysander, the boy he raised and hid from the world for a decade, and with him goes the last of the restraint Lysander had been claiming for himself. Darrow gets away, carrying the loss of the friend who had finally become an ally again. Lysander stops arguing with himself: he accepts what he has done and what he means to do next, and the Gold cause acquires a leader who no longer needs Atalantia's permission to be ruthless.

Darrow goes north into the ice, to the Obsidian strongholds and to a people his revolution freed and then abandoned, who have no reason left to trust anyone flying the Republic's colors. Winning them happens on their terms rather than his, and it costs him. Lyria's pursuit of Volga takes her among the Ascomanni, the Obsidian raiders of the deep dark, in places outside any government's authority. Lysander consolidates his position inside the Gold command, and the balance between him and Atalantia shifts steadily in his favor while the Republic's remaining worlds brace for what he intends to do to them.

Darrow is no longer a castaway. He has an army again: an Obsidian force won on their own terms, together with a scattering of Republic survivors and improbable allies. What he has become in the process is harder to name, and the people who knew him before can see the difference. Lyria's search for Volga carries her to the far edge of the settled worlds. Lysander's ascendancy among the Golds is effectively complete, and his intentions for the Republic have hardened into something even the Core's own commanders find alarming.

Darrow is reunited with Sevro and with survivors he had counted as lost, and the last part of the book is the reassembly of both an army and a man who looked finished. He goes back to the war with the Obsidians behind him and a clearer sense of what he is fighting for than he has had since the revolution. Cassius au Bellona is dead at Lysander's hand, and Lysander ends the book the dominant figure of the Gold cause, having eclipsed Atalantia in prestige and abandoned the last of the scruples he used to argue from; his campaign against the Republic's worlds turns openly and deliberately terrible. Virginia holds the Republic together on Luna, weaker than ever and still refusing to trade it for a dictatorship, with her son safe and her husband alive. Lyria and Volga's stories end far from the war's center. Nothing is decided: the Republic is diminished, the Gold cause is stronger and better led than at any point in its history, and both sides close the book committed to a final war, with Darrow, no longer the myth and no longer the wreckage the myth left behind, heading into it.

Cassius au Bellona is dead, killed by Lysander au Lune, the boy he spent a decade raising and protecting; the killing is the point at which Lysander stops arguing with his own conscience. Lysander finishes the book as the ascendant figure of the Gold cause, his prestige now greater than Atalantia au Grimmus's and his methods no better than hers, prosecuting the war against the Republic's worlds with deliberate terror. Darrow, who began the book a castaway presumed dead, ends it with an army: he has gone into the Obsidian strongholds and won their people on their own terms, he is reunited with Sevro and with survivors he had counted as lost, and he has come back to himself as something other than either the myth or the wreckage the myth left behind. Virginia still holds the Solar Republic on Luna, weaker than at any point in its short life, with her son safe and her husband alive, and she still refuses to save the state by ending it. Lyria's search for Volga has carried both of them far outside the war's center. Nothing is resolved: the Republic is diminished, the Gold cause is united behind a better and more dangerous leader than it has ever had, and both sides are committed to a final confrontation.
