Some books hold stories. This one writes destinies. In blood. When 17-year-old Rivan Kael uncovers The Book of Darkness, he thinks it's a relic. But this book chooses names... and those names vanish. As Rivan is dragged deeper into a world of unseen watchers, bleeding memories, and irreversible sacrifice - the Book demands its final name: "Who do you love the most?" With reality fracturing and time bending, Rivan must choose between salvation and destruction. In the end, the darkness isn't in the book. It's in us.
