Query: Philosophy in novel form

An amazing book written based on the practical yet innovative ideas of Rand. I had read Anthem, and this book is a lot more interesting, both in plot and philosophical implications. I had just taken a macroeconomics course, and I believe knowing a little about basic economic theories enhances the book. It was hard to stop reading, because you want to know what happens to the characters, and at the same time you flinch because of the quasi-communistic and self-destructive ideas of the society. The reason why I didn't give this book the full 5 stars is because while an incredible book, it is really long, and kind of unnecessarily so. Rand uses long monologues to repeatedly hammer her ideas into your head in case you didn't get it the first several times. But a good book just the same, check it out.
