Allegiance picks up two days after A Pound of Flesh left off.
Outbreak - Day 15. With an estimated 99 percent of the United States' population having already succumbed to the rapidly spreading Omega virus, and countries and cities worldwide teeming with the dead, the struggle to survive the zombie apocalypse continues unabated in the high desert of Colorado.
Having just returned from a hastily thrown together secret mission that saw Robert Christian - the self-proclaimed President of his "New America" - snatched from his mountain redoubt and delivered kicking and screaming to the justice awaiting him at Schriever Air Force Base, Cade Grayson, father, husband, and Delta Force operator, is horrified to learn that during his absence the base had been compromised, putting his family in harm's way.
Its inhabitants still reeling from Pug's act of terror, and recently rocked by an undead outbreak inside the wire, Schriever no longer seems an island of safety surrounded by a sea of dead, but more like a shadowy prison, danger lurking within its walls.
So, with the Z-infested cities of Denver and Aurora to the north and 100,000 flesh eaters inhabiting Pueblo to the south, and all hope of a cure for Omega dwindling faster than the world's population, Cade uses a mandated two-day stand down to fully weigh out his options.
With each passing day, he finds himself warming to Brook's stance that they pull up stakes and put the acres of squat buildings and fenced-in concrete in their rearview mirror for good.
With his allegiance walking a tightrope between family and flag, will Cade appease Brook and move the family to Logan Winter's compound outside of Eden, Utah? Or will he lobby her to allow the family to stay at Schriever, so that his Delta Team - still recovering from the recent loss of soft-spoken Sergeant Darwin Maddox and the Unit's longtime commander General Mike Desantos - will not find themselves undermanned and outgunned should another important mission crop up?
Or will the talented Mister Murphy - of Murphy's Law fame - throw a monkey wrench into the equation and alter the best laid plans of mice and men?
