The Idle Brain - Terrence Bertin - Bog

Faithless clergyman Simeon Cole is spirited into the psyche of a
comatose, dying criminal. His task is to awaken the criminal and
combat the legions of demonic forces holding sway in the Inner World.
Simeon must pass through many challenges and tribulations with all the
Powers of the Inner World bent on his destruction. Accompanied by
several companions -- fragments of the criminal's own mind, Simeon
journeys through the bizarre science-fiction and fantasy world made
and controlled by the demonic Powers. If he succeeds, he can escape
the Inner World; failure means his own life. But success also means
losing the only real and meaningful friendships he has ever known. It
is a fearsome task for a clergyman with no faith and no stomach for
adventures. In any case, Simeon must conquer his own flaws and come
to terms with his God to emerge as something more.
