The Luminous Ones

When an otherworldly being crosses paths with Gabriel, a psychic investigator living in the year one billion, his world gets turned upside down. As missing pieces of his past suddenly emerge, Gabriel realizes that his dreams of a coming apocalypse are true. Now, he must assume the mantle of The Last Steward of the Light. His only hope lies in an old book of magic his grandfather gave him, and the unlikeliest of friends—the Angel of Death.
