Childhood's End

Childhood's End is a novel by Arthur C. Clarke, originally published in 1953 (but based off of a 1950 short story of his). The plot concerns the Benevolent Alien Invasion of a race called the Overlords. After stopping the Cold War and establishing a world government, they maintain peace on Earth, but refuse to show themselves for fifty years. Humanity enters a golden age, before spoilery events happen. Yeah, you can't read much more than that without the entire plot being given away.

As suggested by the title, the main theme of the book is the end of humanity's "childhood" into a new era.

Shout Outs to it in fiction are not uncommon, ranging from some in Stargate SG-1 and Xenogears to the cover of Led Zeppelin's ''Houses of the Holy", and the Genesis song "Watcher Of The Skies".

Tropes Used:
""...I am also informed that its opening is identical to that of Childhood's End (1953) and that it contains every known science fiction cliché since Méliès' A Trip to the Moon (1903).""
 * Adaptation Expansion: The first part of the novel is basically a slightly-altered retelling of Clarke's short story "Guardian Angel". The second and third parts are original, about what happens after.
 * Ancient Astronauts: The myths aren't from memory, but precognitive visions of the aliens.
 * Ascend to a Higher Plane of Existence:
 * Assimilation Plot
 * Now you know.
 * Bittersweet Ending, bordering on Downer Ending
 * Bizarre Baby Boom: Aliens show up shortly before a bizarre new generation of humans appears, but they didn't cause it.
 * Blue and Orange Morality
 * Creepy Child: The telekinetic children.
 * Dark Is Not Evil: The aliens were actually the good guys....
 * End of an Age: Following a variation on the theme, the setting is Science Fiction instead of the usual fantasy.

 * Gainax Ending: Indeed, probably one of the most direct inspirations for the Trope Namer.
 * Genetic Memory: Discussed then inverted.
 * The Great Politics Mess-Up: Semi-averted, see Orwellian Retcon below.
 * Hive Mind: A big galaxy spanning one.
 * Humanoid Aliens
 * Last of His Kind: Lampshaded. "He had always been a good piano player, and now he was the best in the world."
 * Older Than They Think: Clarke joked in his updated prologue that new readers will think that the opening scene with the fleet of alien ships blocking the sun was ripped off from Independence Day (despite this being written in 1953!). In fact, Clarke himself knew of an even earlier story with the same scene.
