An ARKANE Thriller by J.F. Penn
Gates of Hell
For millennia, they have held the gates of Hell shut against the darkness. But now they're gone… and the gates are swinging wide.
A letter from Morgan's dead father names her the last of the Remnant, guardian of a Key that must never be used.
From the towers of the Sagrada Familia through the old Jewish quarters of Spain to the salt caves of the Dead Sea, Morgan and Jake follow her father's trail while a man who calls himself Adam Kadmon gathers sacrifices for a night when the veil grows thin, at a castle built not to keep invaders out, but to keep something in.
Those who seek the Gates of Hell must not find the Key.
