In rereading this trilogy after many years (read decades), I was happy to note that Kurtz's writing, characterization, and world-building remain just as strong and original as they were back in the day.
That remains true of this final volume. So, first and foremost, if you have never read Kurtz's work you are in for a treat.
Having said that, I did find that the plotting of book 2 was less successful than that of book 1, and sadly the trend continues here. Oh, it's cohesive enough and carries on with the overarching storyline begun in Camber of Culdi. The main problem is that it is a bit predictable and, worse, ends with enough loose ends to suggest further volumes were on the way. To my knowledge, though, that never happened, leaving this reader, at least, feeling disappointed and unsatisfied. Still, the books strengths are legion so I will give it 3 stars.
