It appears there's a general consensus White Witch is an improvement over Sky Pirates, so I think you can look forward to that.
Oh thank God for that! Seriously, I really enjoyed the MacGregor novels. They're nothing deep and aren't the best Indy tales ever told, but they do a decent job of capturing the character at a younger age and building him towards the man he is in the movies. The adventures/plots were simple, but Indy-like enough to work, and he knew how to keep the adventure moving, the characters at least mildy interesting, and how to hook readers into the next chapter with worthwhile cliffhangers.
Caidin does none of these things. His characterization is flat and wooden. His action is too few and WAY too far between. Its blaringly apparent he's trying to seem smarter than he really is with his useless exposition and descriptions. And his leg-humping obsession with airplanes completely overtakes the Indy tale Sky Pirates should've been. Sorry to those who enjoyed his novels, but I have to say Caidin sucks (at least so far). I very much hope White Witch is a vast improvement.
I haven't read the McCoy novels yet, but have heard good things about them. Most people I notice tend to prefer his novels, even over MacGregors', so I'm looking forward to those.
