Gabriel de León has saved the Holy Grail from death, but his chance to end the endless night is lost. Drawn into an uneasy alliance with the mysterious vampire Liathe, Gabriel must now deliver the Grail to ancients of the Blood Esani, and learn the truth of how Daysdeath might be finally undone.

But the Last Silversaint faces peril, within and without. Pursued by terrors of the Blood Voss, drawn into warfare between the Blood Dyvok and duskdancers of the frozen Highlands, and ravaged by his own rising bloodlust, Gabriel may not survive to see the Grail learn her truth.
