In fact, the universe and I have a rocky relationship and are in a constant fight. So, I hope you know that the universe is telling my story wrong. I am not a genius, I am not an innovative visionary and more importantly: I AM NOT GAY.

But when the game takes on a life of its own… will Daniel still be the one in control?
