Ariel and Nick face their deepest fears and their greatest challenge as they search for the Master Demon who holds the key to the future of mankind. Slay him and the world goes free; fail, and it falls irrevocably into violence and chaos.

Guided by a wisdom master of a mystical tradition that uses mind power as the basis of powerful magic, the assault party travels from the ancient granite walls of the Hermitage, up the Steps of Death, and through a labyrinth of shifting gorges to the Palace of Skulls. Even if Nick wins his struggle with the scars of his past and defeats the green-eyed head of the Cogin clan, they still must cross the scree slope, where the bones of Ariel''s father lie, to get to the ice caves beneath the summit where the Master Demon awaits.

The journey is extraordinary, the enemies are deadly and the ending is mind-blowing.
