Yudkowsky's fanfiction "Harry Potter and the Methods of Rationality" is a fun and easy introduction to the topics of rationality and cognitive biases. The plot is interesting and Yudkowsky manages to fit in ideas from the world of rationality in every chapter. My favourite quote: "I quit, said Harry's mind. Find yourself a different computing substrate to solve your ridiculously overcostrained problems" :-)
