“You will suffice.”Raizen heard those words the night something chose him to survive.He doesn't know what whispered inside his head. He doesn't know why.

Waiting. Pulling strings he can't see.If he wants to survive, he needs to get stronger.If he wants answers, he must become someone even the nightmares fear....But to win?He may have to end anything in his path - and pray he doesn't give the whisper exactly what it wanted all along.
