Nothing can hold back the tide of change.Only four of the ten vampire hives in Britain still exist - others have imploded under the weight of the growing human food shortage - but still, Connor's work on a blood substitute, designed to liberate humans from vampire rule, meets with stubborn resistance.Principal Julian, Connor, and every vampire of status, become so focused on their own plans, that they are blindsided by a global uprising. Feral vampires, like a plague of locusts, sweep across Europe from east to west, until all that stands in their way is the English Channel. Malachi's desperate plea for help galvanises Connor into action, taking him on a treacherous mission to Egypt to rescue his maker which brings home the devastating impact of the coming invasion.Enemies in the shadows, bearing grudges that span decades, conspire to bring down Doctor Connor once and for all, using the army of the undead which no one can defeat. Julian, Connor and Rebekah face the threat head on, but with traitors inside the gates, every move they make accelerates them towards an explosive catastrophe.When ferals cross the seabed, Connor's world spirals into the abyss, death and destruction stalk him and those he loves, and there can be no winners in the final battle.
