Title: The Sighs of Suzumiya Haruhi
Author: Nagaru Tanigawa
What it's about: Suzumiya Haruhi gets the idea to make a movie for the school's cultural festival, and she drags Kyon and the others into it. Haruhi charges into the matter with her usual enthusiasm, and as she pushes for excellence, the lines between fiction and reality start blurring, much to the dismay of the four other Brigade members, especially Kyon, as Koizumi tells Kyon that he's responsible for making sure Haruhi doesn't cause any permanent damage to the world.
What I thought: This is where you really get a sense of Haruhi's powers and her craziness. Some of the things she comes up with are really just hysterical. More of the mystery surrounding Haruhi and her powers is discussed, too. I dunno, this book was never as interesting to me as some of the others. It's still very good, though, and it continues the story of Haruhi, Kyon, and the SOS Brigade.
Overall: If you liked The Melancholy of Suzumiya Haruhi, continue on and read this book.
