There was a TV series called The First Wave, in which there were 5 waves of an alien invasion, which really sound a lot like the five waves described above... and the aliens "the Gua" also look human...theres even a monologue in the show that is JUST like the description of the 5 waves for this book! HA... Anyone else see the similarities???? https://en.wikipedia.org/wiki/First_Wave_%28TV_series%29
