At All Costs

At All Costs is a science fiction novel by American author David Weber, first published in 2005. It is the eleventh book in the Honor Harrington series. Plot summary Because the actions of the High Ridge government in War of Honor led to the Republic of Haven successfully attacking key Alliance shipyards, the Star Kingdom of Manticore finds itself disadvantaged in the ongoing war, with at least two years before any significant new construction may begin. Admiral Honor Harrington is placed in command of Eighth Fleet, the Manticoran Alliance's primary offensive force. Strategically, the Eighth Fleet plans to instill enough operational caution and sensitivity to losses in Haven to force redeployments of starships in defensive postures, reducing Haven's offensive resources. To expedite this, they are assigned most of Manticore's cutting-edge war-fighting hardware, including the new "Apollo" self-guided missile system, which gives Manticoran missiles a massive range advantage over their Havenite counterparts, and "Keyhole" platforms that increase the efficacy of their own counter-missiles. Their first two raids frighten the Havenite populace somewhat, but on the third, at Solon, a defensive ambush led by Admiral Javier Giscard is waiting for them. Honor is sorely trounced, losing several ships and being forced to abandon a vessel captained by her best friend, Admiral Michelle "Mike" Henke, Countess Gold Peak; Henke is believed killed in action, but survives and is captured as a POW. Honor continues to work closely with Hamish Alexander, now First Lord of the Admiralty, on the military and political challenges facing the Alliance, and they fall into the very romantic relationship the High Ridge government tried to insinuate during War of Honor. She and Hamish are married and conceive a son, Raoul, who is "tubed" while his mother goes into combat and is born before the end of the novel. Emily, assisted by Honor's mother Allison, a leading geneticist, also becomes a mother with Hamish.
