Best Module for a newcomer

[BigP4nda]

So I am bringing my Nephew into the fray of Pathfinder, he's 17 and he is a fast learner so I'm not worried about his catching on.
I don't have a whole lot of free time to be designing worlds or revising the worlds I have already started, so I am probably going to run a module, but I have no idea which one.
Are there any recommendations? something that's easy to learn both for the GM and player. As well as anything that's really exciting and attention-grabbing, or something easy to relate to, like something involving demons or dragons.

Master of the Fallen Fortress is a quick one shot that focuses on the mechanics of the game. I find it an excellent start to get people educated on how the system works, especially things like combat and skill checks and environmental hazards.
