Can you recommend some of the best 2019 science fiction books?

Sure. 'Recursion' by Blake Crouch is a great one. It has an interesting concept about time and memory. The plot twists and turns and keeps you on the edge of your seat as the characters navigate through a world where time is not as straightforward as we think.

I would recommend 'Do Androids Dream of Electric Sheep?' by Philip K. Dick. It's a thought - provoking exploration of what it means to be human in a world where androids are almost indistinguishable from people. Also, 'Ringworld' by Larry Niven, which has an amazing and unique setting of a huge artificial ring around a star.

'Gideon the Ninth' by Tamsyn Muir is quite popular. It's a unique blend of science fiction and fantasy elements. It features necromancers in a far - flung future setting, with a sassy and engaging protagonist that really draws you into the story.

Sure. 'Starship Troopers' by Robert A. Heinlein is a great one. It explores military life in a future where humans fight against alien bugs. It has interesting ideas about citizenship and duty.

I'd also recommend 'The Long Way to a Small, Angry Planet'. The characters in this book are very well - developed. You get to know each member of the spaceship crew and their backstories as they travel through space. It's a heartwarming story about the relationships within the crew and their encounters with various alien species.

Sure. 'The Kaiju Preservation Society' by John Scalzi. It's a fun and imaginative take on the kaiju concept. The story has a great mix of humor, action, and some interesting science - fictional elements related to these giant monsters.

Sure. 'Sea of Tranquility' by Emily St. John Mandel is a great 2023 science fiction book. It weaves together different timelines in a very skillful way. There's also 'The Kaiju Preservation Society' by John Scalzi which has a really fun concept of protecting kaiju (giant monsters).

Sure. 'The Vanished Birds' by Simon Jimenez is a great 2020 science fiction book. It has a beautiful and poignant story that spans different worlds and time periods.

Sure. 'Galactic Empires: Rebirth' is a great one. It shows the rise and fall and then the rebirth of a galactic empire. It has a lot of political intrigue and space battles. Another good book is 'The Nano World' which is set in a future where nanotechnology has transformed everything from medicine to warfare.

Yes. 'Record of a Spaceborn Few' by Becky Chambers is excellent. It's a story about the lives of ordinary people in a space - faring civilization. It's really heartwarming as it focuses on the day - to - day experiences, relationships, and the sense of community among these people in space.

Definitely. 'This Is How You Lose the Time War' by Amal El - Mohtar and Max Gladstone is a 2019 gem. It's a beautifully written epistolary novel about two time - traveling agents on opposite sides. The prose is lyrical and the concept is really engaging. And 'Black Leopard, Red Wolf' by Marlon James, which, while it has elements of fantasy, also has strong science - fiction - like world - building and exploration of different cultures.
