*Any*? Are we forgetting the Riftwar Legacy series?
Krondor: The Betrayal
Krondor: The Assassins
Krondor: Tear of the Gods
I thought K:TotG was passable, but the other two were pretty bad IMO. Unfortunately I'm going to have to re-read them because the person they deal with is a major bad guy in the current serieseseses. I seem to remember that Feist was doing something else while he was writing those 3 books, so they didn't get the attention they deserved. Ah well, too bad.
