Today is the beginning, and tonight is the end...

A Babylonian tomb filled with the skeletons of snakes. Seven seals scattered around the world. A young woman, Lilith, who speaks in tongues before covering herself with living serpents. The Brotherhood of the Serpent sees it all, and knows the time of their greatest prophecy — set to occur under a pattern of stars that only align once every four thousand years — is at hand.

Soon the leader of the Brotherhood — Samael, known as Venom, the Angel of Death — will fulfill his destiny: to give Lilith the venom that will summon the Great Serpent to consume the world.

The only thing standing in their way are Morgan Sierra and Jake Timber, the top agents of ARKANE.

A secret British agency tasked with protecting the world from supernatural powers, ARKANE has long operated in the shadows to keep the world safe.

But not even Morgan and Jake can guess at the danger they're about to face. A danger that will take them from the ruins of Iraq to the mist-wreathed Appalachian Mountains, from ancient archeological sites in Israel to the tombs of Egyptian pharaohs — Morgan and Jake have to move fast if they want to stop Samael and Lilith from fulfilling their destinies.

Darkness holds sway. The stars align. And Morgan and Jake will have to sacrifice all they hold dear to have a hope of stopping the End of Days.
