The main-line novel series, primarily following the adventures of the titular character and events on and around Manticore, as well as those in the (People's) Republic of Haven and the Protectorate of Grayson. Among others.
On Basilisk Station: When the prototype weapon mounted on Honor's light cruiser HMS Fearless fails to work as well as its designer wished, she and the crew are sent off to the eponymous backwater where Honor's old enemy Pavel Young is in command, the natives are troublesome, and Haven is behaving suspiciously.
The Honor of the Queen: Manticore sends a delegation to Grayson, hoping to form an alliance, but the other side's sexism makes things difficult, and Haven is working through their old enemies Masada against them.
The Short Victorious War: Haven attempts to thrust further into Manticoran alliance territory, but the threats to the existing Havenite system are not solely external this time.
Field of Dishonor: Pavel Young plans a vicious revenge against Honor and succeeds. Though that decision backfires, it still doesn't make Honor's life any easier.
Flag in Exile: Events lead to Honor returning to Grayson to manage her steading, where enemies conspire against her, and Honor finds that even out of space she has more than one battle to fight. Meanwhile, the war intensifies, and Manticore starts to lose momentum.
Honor Among Enemies: Honor is called back from Grayson to command an anti-piracy mission of Q-ships in the Silesian Confederacy, a lawless but important trading market, and finds a few unlikely allies. Meanwhile, Havenite officers frustrated with the current regime try to force a change.
In Enemy Hands: Honor is captured by Haven and is taken to be executed for crimes she was convicted of by Haven following On Basilisk Station, but her capture will have cataclysmic results for the People's Republic.
Echoes of Honor: Manticore grieves over Honor's execution while the emboldened Peeps launch devastating deep raids, but the video of her death is a fake and Honor is actually plotting her escape from a Haven prison planet called Hades — with the help of a few unlikely allies.
Ashes of Victory: Honor recovers from her long stay on Hades while teaching at Saganami Island. The war between Manticore and Haven heats up even more, with major events on both sides that completely change the politics of the conflict. And Thomas Theisman, with the help of a few fellow patriots, finally makes a stand for the Republic he loves.
War of Honor: A cease-fire has held between Manticore and Haven for years. Honor, out of favor with the current Manticoran government, has lost her command, but she's vocally opposed to reduced military spending and considers the new government to be fools. To quiet her, the government gives her a command at a remote outpost near Silesia, but where "The Salamander" is, fires will burn. Meanwhile, the new government of Haven struggles to keep the peace against popular pressure and dangerous political rivals.
At All Costs: Manticore struggles to overcome the loss of so much of their navy due to cutbacks in War of Honor, so Honor commands a fleet equipped with cutting edge technology to make quick strikes deep into Haven territory. Haven sees Manticore's weakness but is terrified by the implications of the new technology, and what they do next causes the war to come to a climax.
Mission of Honor: Honor leads a diplomatic mission to the heart of Haven in order to finally create true peace, but the Solarian League threatens the negotiations by drawing Manticore into a second conflict and tipping the balance of power. Eloise Pritchart takes the risk of her life to clear the air once and for all, and may be the answer to Manticore's prayers. Meanwhile, the mysterious planet of Mesa has dangerous plans of its own.
A Rising Thunder: The Solarian League Conflict continues to grow as the Grand Alliance is formed and begins to knit together, and old wounds start to heal. Meanwhile, the cracks in the Solarian League start to show.
Shadow of Freedom: While Manticore is occupied with the Solarian League, Michelle Henke is confronted with Mesa's latest gambit.note This book continues the plot threads from Storm from the Shadows and doesn't feature the titular character, meaning that despite its advertising it properly belongs to the Saganami Island subseries, and its title reflects this.
Wages of Sin
The Torch sub-series, following events on and around the planets of Torch and Mesa, and the adventures of Victor Cachat and Anton Zilwicki.
Crown of Slaves: Anton Zilwicki leads a small group to the Republic of Erewhon to try and convince it to stay under the Manticoran umbrella. The problem is, Havenite superspy Victor Cachat is there to convince the locals to his side, a group of Solarians are up to no good, and other factions have their own plans.note This novel runs concurrently with War of Honor.

The Talbott Quadrant sub-series, following events in and around the Talbott Quadrant close to the Lynx terminus of the Junction, and the assorted adventures of Michelle Henke, Aivars Terekhov, Augustus Khumalo, Estelle Matsuko, Abigail Hearns, and company.
The Shadow of Saganami: What should have been a boring mission for four midshipmen on their snotty cruise turns out to be rather more than they — or their captain — bargained for. Meanwhile, Provisional Governor Estelle Matsuko is pushed to her limit, and Mesa is, as always, up to no good.note This novel runs concurrently with At All Costs.
Storm from the Shadows: Michelle Henke heads to the Talbott Quadrant in order to protect Manticore's interests from the Solarian League, but has she bitten off more than she can chew? Not if she has anything to say about it...note This novel runs concurrently with At All Costs and the early chapters of Mission of Honor.
Shadow of Freedom: While Manticore and the Grand Alliance try to get a footing in their conflict with the League, Mesa continues to stir up unrest in the Talbott quadrant and its vicinity, trying to involve the Solarians this time.note While this novel started as the second half of A Rising Thunder and is technically published under the main storyline, thematically (and in the name) it belongs to the Saganami Island subseries.
The Young Adult sub-series, focused on Honor Harrington's ancestor Stephanie, the first human to be bonded to a treecat, and her life on Sphinx — set about four hundred years before the main series.
Fire Season: Climbs Quickly needs the help of Stephanie and her fellow humans in helping a Treecat clan endangered by Sphinx's wildfires. Unfortunately, the telepathic treecats have no way of communicating directly with the mind-blind humans. Also, a scientific expedition has gone missing in the forests of Sphinx, including a young man that Stephanie has found herself infatuated with.
