Which are the top 10 underwater science fiction books that are highly recommended?

Definitely 'The Magicians' series by Lev Grossman. It features a world where magic exists and there are different realms that can be considered parts of a multiverse. 'The Stars My Destination' by Alfred Bester also has some multiverse - like ideas in its exploration of space and human potential. 'Annihilation' by Jeff VanderMeer has a strange and mysterious world that can be seen as part of a larger, weirder multiverse.

Another one might be '20,000 Leagues Under the Sea' by Jules Verne. This classic is a must - read. It has amazing descriptions of the underwater life and the adventures of Captain Nemo. It really gives a sense of the mystery and wonder of the deep sea. The technology described in the book was quite ahead of its time, and it still fascinates readers today.

I highly recommend 'The Seven Deaths of Evelyn Hardcastle' by Stuart Turton. It's a mystery - thriller with a unique time - loop concept that keeps you on your toes. 'A Column of Fire' by Ken Follett is also great. It's a historical fiction that continues the Kingsbridge series and is full of political intrigue and complex characters. And 'The Alice Network' by Kate Quinn, which is set during World War I and II and tells the story of female spies.

I highly recommend 'Homegoing' by Yaa Gyasi. It's a beautifully written book that traces the generations of two families, one in Ghana and one in America. It shows how their lives are interconnected by history and the legacy of slavery.

'These Broken Stars' by Amie Kaufman and Meagan Spooner is also a must - read. A pampered socialite and a jaded military hero are the main characters. Their spaceship crashes on an uncharted planet. As they struggle to survive, they also start to develop feelings for each other. The story has elements of mystery, danger, and a very sweet love story set against a science - fiction backdrop.

The movie 'Interstellar' is highly recommended. It features a team of astronauts exploring a wormhole in search of a new habitable planet. The visuals are stunning and it delves deep into scientific concepts like time dilation. Another great one is 'Blade Runner'. Although it's more about exploring the nature of humanity in a future, dystopian Earth, it still has elements of exploration in terms of uncovering the secrets of the replicants. 'Avatar' is also a top exploration science - fiction movie. It shows the exploration of the lush alien world of Pandora and the interactions between humans and the native Na'vi.

One of the highly ranked science fiction series is 'Dune' by Frank Herbert. It has complex world - building, political intrigue, and a deep exploration of human and environmental themes.

One highly recommended science fiction book is 'Dune' by Frank Herbert. It has a complex and immersive world-building with its desert planet Arrakis and the valuable spice. Another is '1984' by George Orwell. It's a dystopian science fiction that warns about totalitarian regimes and surveillance. 'The Hitchhiker's Guide to the Galaxy' by Douglas Adams is also great. It's a humorous take on space travel and the meaning of life.

I'd recommend 'Flight Behavior' by Barbara Kingsolver. It deals with themes like climate change and the impact on a rural community. It has really engaging characters that draw you into the story.

Well, 'The Hitchhiker's Guide to the Galaxy' by Douglas Adams is really popular. It's a hilarious and absurd take on space travel and the universe. 'Ender's Game' by Orson Scott Card is another top pick. It tells the story of a child prodigy in a military - like setting for space battles. And 'Foundation' by Isaac Asimov, which has an epic scope of a galactic empire's fall and rise.
