The Dragon Factory picks up shortly after the events of Patient Zero as the Department of Military Sciences is faced with a new, completely different threat. This time around there is no zombie plague but rather a planned extinction wave targeted to wipe out a specific large portion of the human population. With the concepts of eugenics, genetic manipulation, and disease weaponization all taken to mad scientist levels the DMS must beat the clock to figure out who is behind the threat and neutralize it before the Extinction Clock counts down to zero. The story is a bit more complex than the first book and therefore starts slower but it eventually comes together and builds to a satisfying crescendo.
