Haruki Murakami is an INFP and mostly writes about INFPs too. His books are atmospheric, slightly philosophical, yet not difficult, and very informal. There's no hurry to get anywhere with the plot, it's about how it makes you feel. Generally his characters are lonely, passive and melancholic with an appreciation for the little things. They're easy to relate to for us, I suppose, and fun to be with. Surreal things tend to eventually happen, and there are cats. Norwegian Wood is my favorite, and is just a really good story about love. If you're more interested in the surrealism he's known for, Kafka on the Shore is probably for you, or if you're in the mood for a brick, The Wind-Up Bird Chronicles, which is this epic story about an unemployed man looking for his missing cat in his neighbourhood. Over the years I've somehow read everything by Murakami, even things have never been officially published in the West, so I guess his books are my favorite.
