What are the most popular fun adventure science fiction books?

Fun adventure science fiction books often have exciting settings. They might be set in far - off galaxies, like in 'Star Wars' novels, where new planets and species are discovered. They also usually have a brave protagonist who is willing to take risks. For example, in 'The Hunger Games' trilogy, Katniss is constantly in dangerous situations and has to use her wits to survive. Another characteristic is the presence of cool technology or scientific concepts. In 'Iron Man' comics, the high - tech suit is a big part of the adventure.

One of the most fun science fiction books is 'The Hitchhiker's Guide to the Galaxy' by Douglas Adams. It's filled with absurd humor, like the concept of the answer to life, the universe, and everything being 42. Another great one is 'Ender's Game' by Orson Scott Card. The battle room scenes are exciting and the story of Ender's journey is engaging. Also, 'Ready Player One' by Ernest Cline is really fun. It's a virtual adventure full of 80s pop - culture references that take you on a wild ride through a digital world.

I'd suggest 'Starship Troopers' by Robert A. Heinlein. It has intense military action and adventure in a science - fiction setting of a war against alien bugs. 'Ready Player One' by Ernest Cline is also fun. It's set in a virtual reality world filled with 80s pop - culture references and great adventures as the main character hunts for an Easter egg. A third option could be 'Dune' by Frank Herbert. It's a complex and epic adventure in a desert planet with political intrigue, advanced technology, and a hero's journey.

I would recommend 'Hyperion' by Dan Simmons. The story is an epic adventure across different planets and through time. It has a complex and interesting group of characters, each with their own story to tell. 'Red Mars' by Kim Stanley Robinson is another great one. It focuses on the colonization of Mars and the many challenges and adventures that come with it. There are scientific elements as they try to terraform the planet. Also, 'Ready Player One' by Ernest Cline is a fun read. It's set in a future where people escape into a virtual world filled with references to 80s pop culture, and the main character goes on a big adventure to win a huge prize.

A popular 2016 science fiction adventure book is 'Seveneves'. It's about the end of the world as we know it when the moon breaks apart. Humanity has to come up with a plan to survive, and the story follows their efforts in space. It's full of scientific concepts and exciting plot twists.
