Ocyrhoe, a young, cunning fugitive from Rome, safeguards a chalice of
subtle but great power. Finding herself in France, she allies with the
persecuted, pacifist Cathar sect in their legendary mountaintop
stronghold, Montségur. There she resists agents of the Roman Church and
its Inquisition, fights off escalating, bloody besiegement by troops of
the King of France, and shields the mysterious cup from the designs of
many.
Percival, the heroic Shield-Brethren knight from The Mongoliad,
consumed by his mystical visions of the Holy Grail, is also drawn to
Montségur--where the chalice holds the key to his destiny.
Arrayed against Percival and Ocyrhoe are enemies both old and new who
are determined to reveal the secrets of the Shield-Brethren with the
hope of destroying the order once and for all.
Alive with memorable characters, intense with action and intrigue,
Siege Perilous conjures a medieval world where the forces of faith
confront the forces of fear. Choices made by characters in The
Mongoliad reach their ultimate conclusion in this fifth and concluding
novel--and all of Christendom is at stake.
