As missing pieces of his past suddenly emerge, Gabriel realizes that the 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.
