Very creative. First in the Eden Trilogy, which is speculative fiction- what if dinosaurs did not become extinct, rather formed a parallel civilization which interacted with the civilization of Man? A lesser author could easily have bungled this premise, producing a hoaky B-movie script. Instead, Harrison lets the characters drive the book. You just accept the premise because you like the characters so well. This is one of those series I feel deserves more widespread public appreciation. Oh well.
