Cover Summary[]

The Star Kingdom of Manticore and the Republic of Haven have been enemies for Honor Harrington's entire life, and she has paid a price for the victories she's achieved in that conflict. And now the unstoppable juggernaut of the mighty Solarian League is on a collision course with Manticore. The millions who have already died may have been only a foretaste of the billions of casualties just over the horizon, and Honor sees it coming.
She's prepared to do anything, risk anything, to stop it, and she has a plan that may finally bring an end to the Havenite Wars and give even the Solarian League pause. But there are things not even Honor knows about. There are forces in play, hidden enemies in motion, all converging on the Star Kingdom of Manticore to crush the very life out of it, and Honor's worst nightmares fall short of the oncoming reality.
But Manticore's enemies may not have thought of everything after all. Because if everything Honor Harrington loves is going down to destruction, it won't be going alone.


After the destruction of the Gamma Center, Mesa launches a propaganda campaign to discredit Anton Zilwicki as a mass murderer, while the secretive Mesan Alignment Navy prepares for the execution of its long-planned Operation Oyster Bay. Meanwhile, Admiral Honor Alexander-Harrington is sent to the Haven System to once again offer peace talks to the Republic of Haven. And in the Talbott Quadrant, Michelle Henke tries to strengthen the Star Empire of Manticore's position as the coming conflict with the Solarian League looms over the horizon.

Fleet Admiral Sandra Crandall arrives in the Spindle System with the Solarian League Navy's Task Force 496, demanding Michelle Henke to be turned over for what she did in the Second Battle of New Tuscany. Henke and her Tenth Fleet, however, are prepared for the Sollies and thoroughly beat them in the Battle of Spindle; dozens of ships and a total of almost 400,000 prisoners of war fall into Manticoran hands.

While Honor continues the peace talks on Haven, Queen Elizabeth III of Manticore, upon receiving the news of what happened in Spindle, orders all termini of the Manticore Wormhole Junction to be shut down for Solarian commercial traffic, as the Star Empire is now in a de facto state of war with the Solarian League.

Some time later, Operation Oyster Bay finally strikes: graser torpedoes and missiles are launched against multiple targets all over the Manticore System. The space stations Hephaestus, Vulcan, and Weyland are destroyed, and the debris hitting the planet surfaces beneath them causes terrible damage. On Sphinx, seven and a half million humans and almost one percent of the entire treecat population are wiped out. The attack has catastrophic consequences for Manticore's economy and military strength: most of the workforce trained to build ships of war is gone, as is most of the missile-building capacity. Twelve million people have been killed, and no one even knows where the attack came from. Queen Elizabeth, however, makes it clear that she will not allow her Empire to fall before its enemies.

Honor is recalled to her home system, where she learns that a large portion of the Harrington Clan was killed when the city of Yawata Crossing was hit by debris from HMSS Vulcan. Other loved ones among the casualties include Andrew and Miranda LaFollet as well as the treecat Farragut. Stricken with grief, Honor swears in the comforting arms of her husband, Hamish Alexander, that she will not rest until she has found and killed the ones responsible for what happened.

However, things continue to get worse: Yeltsin's Star has also been attacked, and while the damage is limited to the outlying Blackbird Yard, High Admiral Wesley Matthews is among the casualties. Judah Yanakov is recalled to Grayson to replace him. At the same time, First Space Lord Thomas Caparelli takes full responsibility for the Navy's inability to protect Manticore, and offers his resignation to Earl White Haven and Queen Elizabeth; both of them refuse to even consider replacing him.

Back on Earth, the Solarian authorities are preparing their response to the Battle of Spindle, and news of what happened to Manticore only encourages them. A force of hundreds of ships of the wall under the command of Fleet Admiral Massimo Filareta is dispatched to the Manticore System to crush the Star Empire once and for all. Meanwhile, an ammunition shortage forces the RMN to recall some of its more modern weapon systems from the Talbott Quadrant. Both Haven and Manticore learn of the Solarian attack from a high level source on Beowulf.

At the Mesan Alignment Navy's secret headquarters in the Darius System, Albrecht Detweiler congratulates his officers for the successful execution of Oyster Bay, and announces that their long anticipated march to dominion over all of humanity is now at hand. With the destruction of the Manticoran space stations, one of the Alignment's most powerful enemies has been as good as neutralized. Soon, the centuries-old Mesan plan to destabilize the Solarian League and give rise to a new star nation under their control – the Renaissance Factor – will be put into action.

Yet, at the same time, Victor Cachat and Anton Zilwicki return to Haven, and with them comes Dr. Herlander Simões, a Mesan defector who can give testimony to many of the Alignment's secretive plans. President Eloise Pritchart begins to realize that the assassination of James Webster, the death of Yves Grosclaude, the outbreak of the war, and possibly even the very rise to power of the Legislaturalist regime, may actually have been elaborate Mesan plots.

In May of the year 1922 Post Diaspora, word of the upcoming Solarian attack on Manticore gets out. Queen Elizabeth addresses her subjects via holovid, and announces that if the League wants a war, it will get a war.

A few days later Haven One arrives in the Trevor's Star System with President Pritchart and much of her cabinet as well as Victor Cachat and Anton Zilwicki aboard. The long delayed first meeting between the Queen and Empress of Manticore and the President of the Republic of Haven takes place in Honor Harrington's quarters aboard her flagship. Elizabeth III learns the truth about the Mesan threat, and within hours, she and Eloise Pritchart decide to not only end the Second Havenite-Manticoran War, but to also form a military alliance against the Solarian League and whatever other enemy may come their way.


The Shadow of Saganami and Storm from the Shadows both focus primarily on the events in and around the Talbott Cluster, while Crown of Slaves and Torch of Freedom focus on the covert war between Torch and Mesa, as well as the moral issues of genetic slavery. Mission of Honor weaves events from both of those areas together and advances the general storyline.

ARC release[]

An unedited ARC version was released electronically on February 3rd, 2010. This version still includes a number of typographical and at least one rather obvious factual error: Henry Prestwick is described to have retired from the office of Chancellor of Grayson around 1920 PD; this character, however, died in the destruction of HMS Queen Adrienne in Ashes of Victory.
