If you haven’t read Flowers for Algernon by Daniel Keyes, then you are missing out on an amazing novel. The novel was first published as a short story in 1959 in The Magazine of Fantasy & Science Fiction.

A sci-fi novel that you will get immersed in is Hyperion by Dan Simmons. It follows a group of people who travel to Hyperion, and the travelers share their stories of how they were chosen for the pilgrimage. The writing, storytelling, and world building make this one of the best sci-fi books out there.

Do Androids Dream of Electric Sheep?

A novel that I loved was Do Androids Dream of Electric Sheep? by Philip K. Dick. It is a brilliant novel that will have you thinking a lot. It is must read sci-fi and the questions in the novel are more relevant today than ever before. Even if you have watched Bladerunner, the original source material is a must read.

Rick Deckard is a bounty hunter in San Francisco and works for the police department. He is given the assignment to retire (kill) six androids that have escaped from Mars to Earth. These androids are new and highly intelligent and are made of organic matter making it difficult to tell them apart from humans.
To tell the androids apart from humans, an empathy test is given to the subject in question. The latest empathy test however is not fully reliable. The Rosen Association tries to get Deckard to drop the case and will go to any lengths to do so.
Deckard heads out and hunts the androids and tries to make them take the empathy test. But this task turns out to be a lot more difficult than Deckard imagined. He wanted to use the money from this mission to replace his electric sheep and buy a live animal for his depressed wife. Now, Deckard must come to terms that the androids he is supposed to kill are more human than anyone could have imagined.

The Hitchhiker’s Guide to the Galaxy

One of my all-time favorite novels and series has to be The Hitchhiker’s Guide to the Galaxy. The writing is brilliant and the humor is timeless. The fate of planet Earth is at stake yet Adams has the reader laughing throughout the book. This novel changed the way I saw sci-fi novels and made me a lifelong fan of the genre.
