Cipher: Echoes of Entropy

Seiyron looks like any modern city. It isn't. Hidden among its people are Ciphers — wielders of impossible power who hold reality together and bury every monster before the world can panic. The cover-up isn't a flaw in the system. The cover-up is the system. Rhys Vaughn was nobody. A runaway with a strange stone against his chest and a pulse that beats in a pattern the universe keeps trying to forget — three, then seven, then twelve. Then something ancient noticed him. The people meant to train him have worked out the truth: he isn't a student. He's a lock. And what's sealed behind him has been waiting a very long time. Only Yuki Vance is dangerous enough to stand in its way — a protector who could end a war in seconds and chooses, every single day, not to. But the world she defends has started to fear her more than the things she kills. And the people closest to her have already begun building her cage. The boy should not exist. Something is about to make sure he doesn't stay that way.
