I'm looking for the name of a science fiction novel from the late 90's or early 2000's.
The plot revolved around a group of genetically engineered young adults that lived in a "pod" or family group. They were potentially telepathic or communicated using pheromones. If I remember correctly, they were chasing someone, a male who fled down to Earth. People still lived on Earth, but were not advanced like the collectivist group in the "pod". I believe they lived on a ring orbiting the Earth?
