This is book number 13 in the Honor Harrington (Audio) series.
Peril and strife strike on a double front for Honor Harrington and company. After a brutal attack on the Manticoran home system, Honor Harrington and the Star Kingdom she serves battle back against a new, technologically powerful, and utterly nefarious enemy. And as if that weren't task enough, Honor must also face down a centuries-old nemesis in the crumbling, but still mighty, Solarian League.
The war between the People's Republic of Haven and the Star Kingdom is finally won and peace established, but grave danger looms--for there is a plan well on its way to completion designed to enslave the entire human species. Behind that plan lies the shadowy organization known as the Mesan Alignment.
Task number one for Honor is to defend against another devastating Mesan strike--a strike that may well spell the doom of the Star Kingdom in one fell blow. It is time to shut down and secure the wormhole network that is the source of the Star Kingdom's wealth and power--but also its greatest vulnerability. Yet this is an act that the Earth-based Solarian League inevitably will take as a declaration of war.
The thunder of battle rolls as the Solarian League directs its massive power against the Star Kingdom. And once again, Honor Harrington is thrust into a desperate battle that she must win if she is to survive to take the fight to the real enemy of galactic freedom--the insidious puppetmasters of war who lurk behind the Mesan Alignment
