FitzDuncan’s Peril (FitzDuncan, #9)

Before they can join battle, mystical instructions divert Fenwick and Caz on a dangerous journey through hostile territory. Waiting for them is a powerful religious artifact, but also a command that they alone must go alone to eliminate the dark mage who is directing the expanding shadow of evil. Caz finds himself in the fight of his life—a contest he is losing until help arrives from an unexpected ally. Thus begins FitzDuncan’s Peril, but before the book concludes, a new narrator must take up the story.

Is this the end for Caz and Fenwick? Do they succeed in eliminating evil, or open a portal for it to spread throughout the world?
