Calculating God★★★★☆
Robert J. Sawyer What if there is scientific evidence out there for a supreme being, but to find it you have to correlate knowledge from multiple inhabited worlds across the galaxy?
Parable of the Sower★★★★★
Octavia Butler Hard to put down. And hard to pick up again. It’s certainly not a fun book, but it’s extremely engaging, despite the bleakness of the slow-apocalypse setting and story.
Paradises Lost★★★★★
Ursula K. Le Guin An intricate novella about the middle generations of a multi-generational spaceship, and the religion they’ve developed that believes nothing outside the ship is real, and both Earth and their destination are myths.
