The fourth book in the best-selling The World Walker series.

Does absolute power corrupt absolutely?

Maybe Seb Varden is in a good position to find out. Depending on your point of view, he has either spent a few days, six months, or 17 years playing a potentially deadly game.

At stake: the freedom of the alien who saved his life, the future of all intelligent species in the universe, and his sanity.

Not only does Seb not fully understand the rules, but it's just possible the game itself is rigged.

So, business as usual then.
