Honor Harrington
Book 11: At All Costs

Nobody does space opera better than Weber, and his heroine, Honor Harrington, introduced in On Basilisk Station (1993), remains as engaging as ever in the latest tome to chronicle her adventures. At the start, intelligence agents of the newly democratic Republic of Haven detect a hidden hand behind their renewed hostilities with the Star Kingdom of Manticore. As the Havenites struggle to convince their foes that they are being manipulated by common enemies among the genetic slave trade, the Manticoreans force their hand until there's no alternative but the Mother of All Space Battles.
