The story
A little girl, a Go board, and a puzzle nobody could solve for twenty years.
Master Glenn is too poor to keep looking after his young student Anna, so he sends her down the mountain to the Nova Go Club and Master Parker Jordan. Overnight the little girl solves the Sovereign Gambit, a puzzle that has beaten every Go player for two decades. Parker takes her in, and then Owl, the ruthless Go King, turns up demanding a match. Anna stays calm and takes him apart one move at a time, until the beaten king is on his knees asking to be her student. Then Parker tells her what he has wanted all his life. He needs to get into the Zenith Go Championship, because that's how he'll learn the truth about how his wife died.
