From publisher blurb:
On 2639.033, forces of the Kilrathi empire land on the human-occupied word of Enyo, putting a quarter of a million human prisoners under orbital guns. Thus began the Enyo Engagement, in which the Terran Confederation executed a masterful plan over the course of one week to drive the Kilrathi from the system.
At least, that's the way the history books say it happens. Whether or not it will actually turn out that way is entirely up to you...
