I Guard The Book That Slays Gods Novel

In a world where fortune always comes at another's expense, Jack Grim—the son of two legendary assassins—has been shaped by a life of violence and ruthlessness. Trained since childhood in the art of assassination, Jack finally receives his ultimate test at seventeen: complete one final mission, and he will inherit his own criminal organization and the life he has always craved. Jack succeeds. His target falls at midnight, and his reward awaits. Yet victory brings only sickness—a crushing headache, a burning fever, and something impossible: transmigration to another world. Jack awakens in the body of Raiden, keeper of the Book of Ashes and guardian of the Devourer's heart. The coward Raiden died protecting this powerful tome, and now Jack inherits both the book and its burden. Desperate to return to his former life as an assassin, Jack finds himself bound by a new obligation: the fate of this entire world rests upon his ability to protect the book he never wanted to possess.
