Jedi Trial is quite bad, but I thought the MedStar books were fun enough.
Night/Dawn kick the crap out of either of them, though
YUCK! I hated Jedi Trial! Everyone was out of character. Michael Stackpole should have written that, since Halcyon was his character!
After a quick Wookieepedia search, I see that Halcyon was originally from the X-Wing novels. Luckily for me I haven't read them yet, so he won't seem out of character to me since this is my first exposure to him.
