This is M2: Maze of the Riddling Minotaur (1983), another invisible ink solo adventure like M1. As large swaths of the interior text are “blank,” I’ve not read it nor can I really comment on it. It looks cool though. I like Greek Mythology and I especially like minotaurs.

Another Timothy Truman cover, though I’m a little meh on this one. Inside is full of Keith Parkinson art, which is truly a gift.
