Time and Again by Jack Finney

[Sarah]

I really loved the trilogy that starts with The Ark by Patrick S. Tomlinson this series starts with End of the World plot as aliens sent a black hole to destroy Earth.

And 14 by Peter Clines has a twisted multiverse.

End of world:
Nemesis: The Demon Star of
Nibiru by William
Prince

And the Ancients series is ramping up to end of the world plot. Its currently 7 books and each one gets more severe.

THE EXTINCTION THREAT: A SciFi
Adventure by T.S. Falk

Michael Salla has a series of books that are all space and end-of-the-world related. These are the books in the series:

1) Insiders Reveal Secret Space Programs & Extraterrestrial Alliances
2) US Army Insider Missions 2: Underground Cities, Giants & Spaceports (Secret Space Programs)
3) Antarctica's Hidden History: Corporate Foundations of Secret Space Programs
4) Galactic Federations, Councils & Secret Space Programs
5) US Army Insider Missions: Space Arks, Underground Cities & ET Contact (Secret Space Programs)

9) Space Force: Our Star Trek Future
10) Kennedy's Last Stand: Eisenhower, UFOs, MJ-12 & JFK's Assassination
11) Galactic Diplomacy: Getting to Yes with ET

Or there is Michael Moorcock's The Sundered Worlds, which was the first book to describe the multiverse. Most of his Eternal Champion stories are set against this background.

Dark Matter by Blake Crouch is another good one on multiverse.

The Hidden Reality: Parallel Universes and the Deep Laws of the Cosmos by Brian Greene

The End of Everything (Astrophysically Speaking) by Katie Mack combines multiverse with a proposed way how each ends.

The Illustrated Man by Ray Bradbury

Earth Abides by (I forget the author's name)

Ender's Game by Orson Scott Card

Foundation by Isaac Asimov

The Moon is a Harsh Mistress by Robert Heinlein

[William]

This is the original first book I read about multiverses when I was a kid, The Number of the Beast by Robert A. Heinlein and then his book Stranger in a Strange Land that isn't about the multiverse per se but about Multi-Universal Solopsism.

I highly recommend the 9 volume sci-fi series, The Expanse by James S.A. Corey, beginning with Leviathan Wakes. It's rated a 4.30 with more than 260, 000 ratings. I was totally immersed throughout all nine.

To Swim in a Sea of Stars by Christopher Paolini is excellent.
