What Happens, Part by Part (Contains Spoilers)
Arrival
During the space race, enormous ships appear over Earth's cities. Karellen, the Overlord in charge, speaks only through the UN Secretary-General, Rikki Stormgren, and never appears in person. The Overlords stop wars and cruelty and set humanity on a new path. Stormgren tries to see Karellen's face, but he glimpses only a shadow.
The golden age
After fifty years, the Overlords finally reveal themselves. They look like the horned, winged monsters of old human legends, which explains why they waited. Humanity, now used to peace and plenty, accepts them. There is no war, little crime and no need to work hard. But creativity and science begin to fade, as people no longer need to struggle.
Questions
At a party, a strange guessing game played in the dark produces the name of the Overlords' home star. A young scientist, Jan Rodricks, uses this clue to stow away on an Overlord supply ship. Because of time dilation, his trip will take only a few months for him, but about eighty years will pass on Earth. Meanwhile, a group of artists founds an independent colony, New Athens, to keep human culture alive.
The children
In New Athens, George and Jean Greggson's son Jeff begins to have strange dreams of distant worlds. Soon all young children on Earth change. They stop speaking, develop psychic powers and form a single collective mind. Karellen explains that the Overlords are “midwives,” sent by the Overmind to guide humanity through this transformation, which they themselves can never experience.
The end
The older generation cannot follow its children, and many lose hope. The children leave their physical bodies and join the Overmind, and the Earth itself dissolves. Jan, returning from the Overlords' world, is the last human left. He describes Earth's end to Karellen by radio before he dies. The Overlords leave, still searching for meaning in the universe.
5 Key Takeaways
- Peace and comfort can lead to stagnation.
- Progress may require letting go of the familiar.

- Advanced powers may have limits too.
- Endings can also be new beginnings.
