Of all the Weis & Hickman books, this trilogy was my favourite. Looking back, it was the most original and interesting (in terms of characters, world building and premise). Far outshining the much beloved (and far more well known), formulaic "Dragonlance" books that preceeded it. Freed from the shackles of having to write a fantasy trilogy as a companion piece to the D&D module packs, they were able to explore their imagination more fully and structure the plot more appropriately.
Okay, if I read it now I probably wouldn't rate it quite as highly but I still think that it stands up fairly well, unlike most other books they wrote before or since.
