With the ninth book, Chainfire, the Sword of Truth series starts the final story arc, that will continue through the final two books to the conclusion of the series.

Chainfire is the beginning of a trilogy of books that completes the Sword of Truth series.  After a battle, Richard awakes to find Kahlan gone.  Even more disturbing is that nobody seems to remember who Kahlan is, or that Richard was ever married.  It is as if Kahlan has been erased from the world without ever having existed.  While desperately trying to convince the others that Kahlan is real, he tirelessly searches for her and for the enemies that have taken her, setting a dark plan into motion.
