Passionate about reading, Elliott has always had a preference for the stories of boogeymen, those monstrous creatures which, at night, hide in the shadows or under the bed to frighten little children. He can\'t imagine how much they will change his life… Witnessing the bloody murder of his parents, he will discover that, in reality, boogeymen do indeed exist, and very precise codes govern their existence. When one of the most powerful boogeymen, "Father-Death," decides to protect him, Elliott finds himself plunged into a terrible conflict at the heart of a universe as terrifying as it is fascinating.
