I need to know if Luke Skywalker used the Force to bring himself back from the dead and what book it was in. I think it was "The Courtship of Princess Leia", but I'm not sure. I would also like to know (if it's true) if it is specified, if the Force itself brought Luke back to life or if it was a direct application of Luke himself.
Well, Luke managed to 'become one with the force' and came back to talk to the living in Star Wars: Legacy 3: Broken, Part 3. He may have done so at other times, but that's the first reference to it that I recall. Not sure if it counts as a book, tho.. It was a comic book series.
Regardless, that's acting as a Force Ghost; if you are looking for resurrection, I don't recall him doing that. The whole Force Ghost thing was also ret-conned after the prequels came out, so YMMV with what it means. Initially, it was something all of the good/redeemed Jedi could do; later it became a rediscovered technique. In 'The New Rebellion' Luke prepares himself for being killed by engaging in the needed technique in advance.
