The book is set in a Manhattan, the year 2118. A 1000-story tower was built in New York, where the wealthiest live in the upper levels. The people who support the maintenance of the tower live in the lower levels. The book is told around five teenagers, and each chapter is from a different character's perspective of the world.
I'm about halfway through right now, and I'm enjoying the book very much. Every free moment I get, I find myself wanting to read a few chapters.
