Two classic novels from a best‑selling master of SF.

Cradle of Saturn
Discoveries made by colonists on the moons of Saturn show that the Solar System has undergone repeated cataclysms and the last was only a few thousand years. This flies in the face of accepted scientific dogma, and is dismissed by Earth’s authorities—until the planet Jupiter suddenly emits a white‑hot Earth‑sized protoplanet that hurtles sunward on a collision course with Earth.

The Legend That Was Earth
The alien Hyadeans have showered high‑tech gifts on the population of Earth and are offering to make a paradise of the planet. But when wealthy socialite Roland Cade discovers the dark underbelly of the alien presence, and learns that his ex‑wife is one of the so‑called terrorists who are fighting against the alien takeover, he’s forced to choose sides. Soon, he’s caught up in a terrifying conflict that threatens the very existence of the Earth.
