I pushed too far—and it killed me.Then I woke up.Sixteen again. Back at the Ritual. But this time, something changed.Time bends at my will. Blood moves when I command it.The gods still won’t acknowledge me, but it doesn’t matter. This world isn’t fair, and I’ve stopped playing by its rules. Faith and Chaos clash in my veins, and I will use them both.They wanted a Chosen Hero, someone to dance to their tune.Well, too bad for them—I’ll carve my own fate.
