Two aliens, Anu and Matrona, who first made their appearance on Earth 5000 years ago to help mankind develop civilization, return after a 2000 year absence. And they're pissed. Instead of cleaning up our mess again, they choose seven humans, calling them angels, teaching them the ways of universal love and joy. Can the angels spread the message in time? Will their opponents succeed in stopping them? Will Anu and Matrona destroy humankind and turn the planet over to the dolphins?
