Humanity faces extinction as the Earth is terrorized by a force from another Universe. The answers to your questions await in the second book of the series: Sheep to the Slaughter. Arlana Tristus and Colin Browne flee from the east as the terror from Stonehenge continues to devour and infect people by the millions. With the world's resources pooled to fight and contain the menace, Arlana seeks answers within the Book of Vigils, hoping to find a way to fight back.
In the first audiobook of the trilogy, I Devour, Therefore I Am, an ancient order must perform a sacred ritual at Stonehenge; the remnants of an ancient prison known to the order as "The Circle of Captivity." Arlana Tristus spent her entire life defying her own destiny, but now she can run no longer. The ritual at Stonehenge has failed, the prison bars have been shattered, and what lies within is unleashed upon the Earth.
As we struggle each day to survive, we remember through the stories we've stolen; it is through them that we have come to know the face of our true enemy. Turn back the clock and witness the events that set into motion the last war this universe shall ever witness.
Everything has been leading to this; the stage is set and the final battle begins for the survival of the human race. Fight until the end in the thrilling conclusion of the trilogy: Accept the Inevitable.
