Gabriel de León has lost his family, his faith, and his last hope of ending the endless night – the Holy Grail, Dior. With no desire left but vengeance, he and a band of loyal brothers journey into the war-torn heart of the Augustin Empire to claim the life of the Forever King. Unbeknownst to the Last Silversaint, the Grail still lives – speeding towards Augustin’s besieged capital in the frail hope of ending Daysdeath forever. But deadly treachery awaits within the halls of power, and the Forever King’s legions march ever closer. Gabriel and Dior will be drawn into a final battle that will shape the very fate of the Empire, but as the sun sets for what may be the last time, there will be no-one left for them to trust. Not even each other.
