I remember my dad bought this book for himself, read it, then gave it to me. I was mesmerized by the cover. It really was weird that it had Darth Vader on the cover but didn't say "Star Wars". Before I took the plunge and read it (I was maybe 9 or 10), I continually asked my dad, "Is it REALLY a Star Wars book?"
Back in the mid 90s I tracked down a copy of Mission to Ord Mantell. I personally thought it was pretty lame.
