A satisfactory, if more average, ending to the cycle. The character arcs from Chainer's Torment are continued here well enough, and the pacing and action are somewhere in between the quality of Odyssey and Chainer's Torment, though definitely leaning toward the later.
After the conclusion of Chainer's Torment, Chainer has been killed in the struggle over the Mirari in Cabal City. Kamahl, his friend and the protagonist of the trilogy, takes the Mirari to fulfill Chainer's dying wish. He journeys to his home, the Pardic Mountains, to attempt to unite the barbarian tribes there under one sword--his. Corrupted by the Mirari, he attacks his sister and believes he kills her, thinking that she had murdered their mutual father figure Balthor. The rest of Kamahl's narrative is spent attempting to undo the damage he did under the Mirari's influence and having a truly interesting character change.
Throughout Kamahl's journey, chapters focused on everybody's least favourite merman Laquatus are sprinkled in. These are the weaker chapters of the novel, but are still nowhere near the agonisingly low quality of Odyssey. Burke is at least a more interesting jack than Turg was, and some of the end-of-book threads with Laquatus attempting to play every faction against one another is at least somewhat entertaining due to how pathetic Laquatus is.
Overall, I definitely recommend Judgment if you enjoyed Chainer's Torment. If you didn't, there's really no reason to continue on to this novel as it's just a slightly less-entertaining continuation of that narrative.
