Can you recommend some 2013 best science fiction novels?

Sure. 'Starship Troopers' by Robert A. Heinlein is a great one. It explores military life in a science - fictional universe. Then there's 'A Canticle for Leibowitz' by Walter M. Miller Jr., which is set in a post - apocalyptic world with a strong religious undertone. 'Slaughterhouse - Five' by Kurt Vonnegut also has science - fiction elements and is a unique take on time and war.

One of the great 2018 science fiction novels is 'The Calculating Stars' by Mary Robinette Kowal. It's set in an alternate history where a meteorite hits the Earth, and it focuses on a female pilot's fight for equality in the space race. Another is 'Record of a Spaceborn Few' by Becky Chambers. It explores the lives of ordinary people living in a vast galactic community. And 'Annihilation' by Jeff VanderMeer is also notable. It takes readers on a strange and mysterious journey into Area X, a place full of odd and dangerous phenomena.

I would also recommend 'Hyperion' by Dan Simmons. It has a frame - story structure where different characters tell their own tales on a pilgrimage to the Time Tombs on the planet Hyperion. The stories are diverse, ranging from a soldier's love story to a scholar's encounter with an alien intelligence, and the overall mystery of the Shrike is very engaging.

A great one is 'Ender's Game' by Orson Scott Card. It follows the story of Ender Wiggin, a child prodigy trained to fight in a future war against an alien race. It explores themes of leadership, morality, and the cost of war.

Then there's 'This is How You Lose the Time War' by Amal El - Mohtar and Max Gladstone. Two agents from opposing factions in a time war communicate through letters hidden in different time periods. Their relationship evolves from enmity to something much deeper, a love that defies the very fabric of the war they are in. It's a beautifully written novella that combines time - traveling concepts with a very unique and tender love story.

Sure. 'Frankenstein' is a must - read. It was one of the first novels to really explore the idea of artificial life. Then there's 'The Invisible Man' by H.G. Wells. It's a really cool concept about a man who becomes invisible and the problems that come with it. 'Around the World in Eighty Days' by Jules Verne is also a great early science fiction novel. It shows an adventurous journey around the world with the help of modern technology at that time.

Sure. 'The Caves of Steel' by Isaac Asimov. It's a great detective story set in a future where humans and robots coexist in a somewhat tense relationship. Asimov's masterful writing makes the world and the characters, both human and robotic, very engaging.

Kim Stanley Robinson's 'Red Mars' is excellent. It tells the story of the colonization of Mars. The book is full of scientific details about terraforming and the challenges of living on another planet. It also delves into the political and social aspects of such a grand endeavor, making it a very immersive read.

'Aurora' by Kim Stanley Robinson is a great choice. The story of the generation ship and the relationships that develop over time among the passengers has a lot of romantic elements. It shows how love can endure and change in the face of the vastness of space and the challenges of a long - term space journey.

Well, 'All Systems Red' by Martha Wells is also great. It features a security android on a mission to Mars. The story is full of interesting characters and unexpected twists.
