In the near future, dysfunctional governments and powerful mega-corporations have created a world of unending violence, leaving it teetering on extinction. Out of nowhere arrives the Host- a mysterious entity armed with the ability to bring instant death to anyone... or everyone... on the planet. The Host has one demand- end the cycle of violence and war immediately or face annihilation. A new era dawns- The Peace. Aided by the Servants of the Host, humanity begins to tackle its root problems; working to achieve what the Host calls The Promised Land. The quest for The Promised Land has its dark side, however. The Host can commit horrible atrocities against those who resist its will- those with much to lose in the new order. Some believe the Host is Satan himself, others believe they are the victims of an alien occupation. Journalist Grace Williams and Special Agent John Harriman find themselves thrown together; she to find the true nature of the Host, he to neutralize its grip on the planet and restore the old order. The two must race against time to uncover the secret of the Host before its too late.
