Fight Club 3. Book 1

Marla is about to give birth to her second child, but its father will not be her husband, now calling himself Balthazar, but Tyler Durden, who is very interested in his child inheriting the entire world. In the previous part, Tyler turned "Project Mayhem" into "Rise or Die" and, when the heavenly gates were so close, the new group executes a ruthless plan to reprogram humanity, prompting Balthazar into a questionable alliance… with Tyler Durden.
