Gandalf Sacrifices Himself for the Good of the Third Imperium
Book 8 robots and adventures 12 and 13 are the only books I do not have now. Been trying to get them but they go for a bit and compatition is fierce. That and High passage 1 and 4. I have gotten 4 of the signed 10s though. 2 adventures and 2 race books. I would love to know more of the history about them though.
I paid around $25 for Robots, it was actually in slightly better shape than the seller stated, as was the copy of Tarsus which I picked up also for $25.
