I know I read Loamhedge but all I remember from it is the wheelchair character suddenly not needing her wheelchair at the end, so that's probably my least favorite.
I enjoyed The Legend of Luke. Always figured from the way Martin the Warrior set him up that he must be having some pretty big offscreen adventures (because if he was just some chump who died in the backstory he might as well have died in that flashback instead of sailing away) so the whole segment with Luke taking the fight to the searats was just about exactly what I wanted on that front, and I'm a sucker for the kind of retracing-the-steps story that makes up the rest of the book in Martin's time - it's part of what I liked so much about the first book, the sort of scavenger hunt for Martin's relics.
