An ancient manuscript that leads to the Gates of Hell. A woman's revenge for the death of her father. When the last of the Remnant is murdered at the Sagrada Familia in Barcelona, ARKANE agent Dr Morgan Sierra is drawn into the hunt for a supernatural Key. She's joined by agent Jake Timber, who must face his own fears as they decipher clues left behind by Kabbalist scholars. From ancient sites in Spain, to Israel and the Czech Republic, Morgan and Jake must follow the trail to the Key, while evading Adam Kadmon, a man consumed with a lust for dark power. As the planets align, Morgan and Jake race against time to find the Key and destroy it before the Devourers and the Polluted of God emerge from the Gates of Hell to ravage the earth. This is Book 6 of the ARKANE supernatural thriller series, but it can also be enjoyed as a stand-alone novel.
