Banner in the Sky

At sixteen, Rudi is determined to pay tribute to the father he never knew. Taking his father's red shirt as a flag, Rudi heads off to face the earth's most challenging mountain. But before Rudi can reach the top, he must pass through the forbidden Fortress, the gaping chasm in the high reaches of the Citadel where his father met his end. Now he must search deep within himself to find the strength for the final ascent to the summit—to plant his banner in the sky. His father died while trying to climb the Citadel and Rudi knows he must make it himself.
