by Robert A. Heinlein (1956)
One minute, down and out actor Lorenzo Smythe was — as usual — in a bar, drinking away his troubles as he watched his career go down the tubes. Then a space pilot bought him a drink, and the next thing Smythe knew, he was shanghaied to Mars. Suddenly he found himself agreeing to the most difficult role of his career: impersonating an important politician who had been kidnapped. Peace with the Martians was at stake — failure to pull off the act could result in interplanetary war. And Smythe's own life was on the line — for if he wasn't assassinated, there was always the possibility that he might be trapped in his new role forever!
Isaac Asimov
The story of temporal engineers who meta-regulate the history of humanity through the centuries, eliminating risk, adventure, and space travel in the process. One man rebels in order to save the existence of someone he loves, and in the end the time bureaucracy is destroyed for the sake of individuality and human achievement. The theme is the opposite of the Foundation stories, where the central planners and manipulators of humanity always dominate.

A time storm has devastated the Earth, and only a small fraction of humankind remains. From the rubble, three survivors form an unlikely alliance: a young man, a young woman, and a leopard. "A masterful science fiction story told by a masterful science fiction writer". -- Milwaukee Journal. A time storm strikes the Earth. The Earth remains, but different parts of the Earth are in different eras. Travel between the different zones is thought to be impossible. The main character, Marc Despard, resolves to fight the time storm. After some struggles, he assembles a small band of people, including one alien, to help him try to understand what has happened and to stop the time storm. He has 2 extraordinary relationships with a older teenaged girl who is speechless for the first part of the book (she was "struck dumb" by the time storm) and with, believe it or not, a leopard. Dickson's writing makes the extraordinary seem quite normal. Ultimately, after being harried by a Mad Max-like group of survivors, he uses a machine found in a different era of time to bring his small band of followers into the future so that he can find those who are trying to fight the time storm. He convinces those future beings that he is capable of fighting the time storm, and ultimately stops it, and gets the girl in the end.
