It appears as if Lucien has won.When Castiel takes off to Terra Enim to sacrifice his life, and fight Lucien himself, Hope will have to make a decision that may affect the rest of the world as we know it. In the final book of the Immortal Opus series, when all hope is lost—A terrible battle will take place at Terra Enim. With great love comes great sacrifice, and in this heartbreaking conclusion—Only one side will come out victorious.
