At All Costs
David Weber
 Due to the actions of the High Ridge government in War of Honor, which led to a successful attack on key Alliance shipyards by the Republic of Haven, the Star Kingdom of Manticore finds itself decidedly on the short end of the strategic balance between the two warring star nations. Admiral Honor Harrington is placed in command of Eighth Fleet, the Manticoran Alliance's primary offensive force, which is the sole heavy formation available for operations against Haven. Queen Elizabeth and her senior advisors project it will be at least two "T-years" (Terran years, i.e. Earth years) before they can expect any significant numbers of new construction to begin bolstering their thin wall of battle; this while Haven's progress under Admirals Theisman and Foraker have given them an even larger force advantage, and smaller technological disparity, than Haven suffered before the beginning of hostilities in Short Victorious War. Strategically, the goal of Honor and Eighth Fleet is to instill enough operational caution and sensitivity to losses in Haven to force redeployments; this would have the desperately needed effect of reducing the available number of ships of the wall Haven would then be able to concentrate for offensive action against the Star Kingdom and its allies. Despite the grave circumstances, the Star Kingdom finds itself spread dangerously thin against its security commitments; to itself and the Alliance. At All Costs climaxes with the largest and most critical battle of the entire series, the Battle of Manticore, as Havenite forces attack the Manticoran home star system. Haven comes close to winning the battle, until Admiral Harrington's Eighth Fleet intervenes, giving Manticore a hard-won victory. Both sides suffer heavy losses, and they are temporarily stalemated. Honor continues to work closely with Hamish Alexander, now First Lord of the Admiralty, on the military and political challenges facing the Alliance. Their professional respect for each other's abilities, and their need for mutual support as they navigate the precarious political landscape in the Star Kingdom, has led them into the very romantic embrace the High Ridge government tried to insinuate during War of Honor. While this is not the dire political crisis it was during the prior Star Kingdom government, it still offers numerous personal and professional difficulties for them. Unfortunately, they find themselves trapped between their emotions and their responsibilities to each other, to the loved ones in their lives, and to the Star Kingdom and the Alliance. The dilemma is resolved when the Reverend of Grayson engineers a polygamous marriage of Honor to Hamish and his crippled wife.
