The Honor of the Queen is a science fiction novel by American writer David Weber, first published in 1993. It is the second book in the Honor Harrington series. On the planet Grayson to participate in diplomatic talks between the Kingdom of Manticore and the Republic of Haven, Honor Harrington discovers that she is stuck on a fiercely patriarchal, misogynist planet. Original.
 Three years after the events in On Basilisk Station, Captain Honor Harrington returns to the Star Kingdom after a long anti-piracy campaign in the Silesian Confederacy. While her ship, HMS Fearless, has her first refit, new orders arrive. Fearless is tasked to lead a small Manticoran squadron supporting a diplomatic mission to the planet Grayson, a planet ruled by a heavily sexist and patriarchal society, due in part to its fundamentalist Christian and Luddite history, as well as its brutally hostile environment. The diplomatic mission is to be led by Admiral Raoul Courvosier, Honor's mentor and personal friend. With the long-awaited war with Haven looming close, Manticore is working to form an Alliance with many small nations. Grayson is critical to this effort, as it would close a flank of advance for a possible Havenite invasion fleet. Adding to the pressure, Haven is negotiating its own alliance with Masada, Grayson's historical rival.
 The Manticoran ships arrive at Yeltsin's Star, the system where Grayson is located, and are greeted by the small Grayson Navy. However, the welcome is soured by sexism in the Graysons, for whom the notion of a woman in uniform is intolerable. After several hostile confrontations, Honor leaves the system to escort a convoy of freighters, believing her presence is souring the negotiations, even though Courvosier tries to convince her not to do so.
 After Honor departs with three of the four Manticoran warships dispatched to Grayson, Admiral Courvosier collaborates with Admiral Bernard Yanakov, the commander of the Grayson Navy, bridging cultural differences and developing mutual understanding. However, their efforts are abruptly halted as a Masadan fleet attacks Grayson, targeting space stations across the system. Facing this threat, Admiral Courvosier accepts Yanakov's offer to join forces against the Masadans. Unbeknownst to them, the Masadans command two Havenite warships under Captain Alfredo Yu and Cmdr. Thomas Theisman. This combined fleet swiftly overwhelms Grayson's outdated defenses, including the Manticoran destroyer Madrigal, resulting in the tragic deaths of both Courvosier and Yanakov.
 Honor's ships return to Grayson and are attacked by Masadan light attack craft, which damaged one of her ships. After entering Grayson's orbit, they are apprised of the critical situation following the battle and the death of Admiral Courvosier. Honor strong-arms Protector Benjamin into allowing her to take a leading role in the defense of Grayson. She also then defends him against Masadan assassins, losing one of her eyes, earning her a great deal of acclaim from the Grayson people.
 Grayson soon learns that Masada has built an advanced base within Grayson's star system. Leading her ships and the remnants of the Grayson fleet, Honor defeats a group of Masadan warships, as well as the PNS Breslau, now fighting as the MNS Principality. Cmdr. Theisman is able to inflict significant damage on HMS Apollo, under Cmdr. Alice Truman, but is ultimately forced to surrender.  Once in confidence, he tells Honor that there are female POWs from Madrigal at the base and that he suspects they are being ill-treated.  An assault by Fearless' Marines follows, and the Masadan base is captured, finding most of the prisoners executed and all the female prisoners horrifically brutalized, with Honor nearly performing an on-the-spot execution of the Masadan commander.
 On Masada, the Havenite "advisers" see that Masada's bid to conquer Grayson is doomed and try to pull out. However, the Masadans find out and seize control of the Saladin, which they have renamed Thunder of God.  Captain Yu catches wind of the mutiny and pulls as many Havenite crew off the ship as he can, leaving the Masadan fanatics in ownership of a Sultan-class battle cruiser that outguns Honor's remaining ships.
 Honor dispatches Apollo back to Manticore for reinforcements, while her Fearless and Alistair McKeon's Troubadour prepare to fight the Masadans. The Manticorans' superior tactical skills, and the Masadans' unfamiliarity with their ship, allow them to inflict much more damage on Thunder of God than they ought to have done, but Thunder of God by sheer weight of fire is able to destroy Troubadour and inflict equal damage on Fearless.  Manticoran reinforcements, summoned by Apollo and led by Admiral Hamish Alexander, Earl White Haven, arrive in-system, but neither Fearless nor Thunder of God are able to detect them due to damage to their radar and gravitic detection equipment. Despite knowing the outcome is hopeless, Honor commits Fearless against Thunder of God hoping to do enough damage to prevent Thunder from carpet bombing Grayson. In a desperate gamble, White Haven's fleet launches from beyond maximum range, distracting the Masadan crew at a crucial moment and allowing Fearless to deliver the killing blow.
 With Grayson secured, a joint Manticore-Grayson fleet attacks Masada and occupies the planet.  Thomas Theisman is returned to Haven. The Havenite refugees from Saladin, led by Alfredo Yu, surrender to the Graysonites; several others defect, including Yu himself.  Honor recovers from the wounds sustained during the numerous battles and the attack on the Mayhew family, receiving a prosthetic eye. Protector Benjamin decorates her with the Star of Grayson and appoints her as Steadholder (governor) of a new fief on Grayson, allowing her to help Benjamin speed up his planned social reforms, a program which comes to be known as the "Mayhew Restoration."  Finally, the Manticoran government creates Honor a Countess and names her a Companion of the Knights of King George.
 The Grayson society introduced in this book has been a subject of academic analysis by Steven Hrotic in his book Religion in Science Fiction.  Hrotic writes that the Graysons represent "positive examples of a religion not because they lack flaws, but because they are willing to admit their flaws, and change".
