Shadowrun. Secrets of power. Book 3. Find your truth

Sam Werner has only recently become a shaman, but he already needs to find a way to heal his sister. In search of a cure, he and his team of runners came to a mysterious cave in Australia, where they... discovered a powerful artifact that could be useful. After all, lifting this curse requires powerful magic. By stealing the artifact, Sam unknowingly unleashed an ancient evil that had been kept from destroying the world for many years. Torn between the need to stop the monster and the desire to save his sister, Sam decides to find the greatest shaman of the Sixth World, the former leader of the Great Dance of the Spirits, a man who may no longer be alive.
