Key Gifford bears the weight of the whole world on his shoulders. As the 13th Devil, Key was born for a specific purpose: either to be a sacrifice-a way for Hell to claim and destroy the earth-or to make a Garden of Eden of our world and grant humans immortality. Key is the single catalyst to Armageddon or deliverance, and being responsible for the salvation or death of humanity is a burden he is desperately trying to escape. In this powerful debut novel, Key and his partner, Elizabeth Hellsing, must find the Shroud of Turin if they are to have any hope of changing Key from the 13th Devil into a human. They'll face unholy opposition at every turn, but if they succeed, it will cancel out the prophecy, free Key from his own sacrifice... and save the Earth from total destruction.
