Hyperion ***** : All four books in this serious are "big" science fiction: society, government, military, time and space travel, religion; it covers it all! (I read these last year but forgot to review them until now.)
Player of Games ***** : Culture series, book 2. Even better than the first! About a master player in a game that determines who becomes emperor.
Consider Phlebas **** : Great space opera with thorough backstory a la David Brin's Uplift series.
Tunnel in the Sky **** : Classic Heinlein space-cowboy, coming-of-age, young-adult fiction.
Borders of Infinity **** : Continuation of story line from Vor Game.
Anathem ***** : Science "monks" sequester themselves from the rest of the world for 1, 10, 100, or 1000 years at a time so that they can solve interesting problems in peace. Takes place on another planet with a whole new vocabulary to learn and enjoy. Based loosely on the Clock of the Long Now.
Sunshine *** : Makes me nostalgic for 2001: A Space Odyssey. Well filmed, but impossible physics and some ridiculous plot gyrations cost this movie a star.
Warlock in Spite of Himself *** : More of the same from Escape Velocity author. Part of the Warlock series.
Earth Abides ***** : Another classic sci-fi novel that I somehow never read until now. A disease kills almost everybody on Earth and the survivors live off the remains of civilization. Epic and thought-provoking!
Escape Velocity *** : Political sci-fi set in a medieval context. A little trite in spots, but better than I expected!
Vor Game **** : Obviously part of a much larger series (which I haven't read), but good by itself. Socio-political emphasis.
Venus Prime 1 *** : Better than I expected and an enjoyable end to my sci-fi reading blitzkrieg while on vacation in Costa Rica.
To Sail Beyond the Sunset ** : Heinlein is either a genius provocateur or just a dirty old man. Either way, this book didn't take for me.
Revolt in 2100 *** : Classic Heinlein space opera pulp fiction. Overly simplistic and unrealistic solutions to social problems, but it's fun reading.
Flowers for Algernon ***** : Another oldie-but-a-goodie that I had never read until now. Great soft scifi.
On Dragonwings **** : This is actually three books bound into one: Dragonsdawn, Dragonseye, and Moreta. All part of the Dragonriders of Pern series by Anne McCaffrey. An interesting blend of scifi and fantasy crossing nearly 2000 years.
Day the Earth Stood Still ***** : One of the best scifi films ever made, over 55 years old and going strong! This is my third time watching it and I still love it.
Triad *** : Finally read this book after 15+ years on my bookshelf. First contact sci-fi novel with a linguistic twist. Not bad, but disappointing ending.
Left Hand of Darkness *****: Outstanding novel full of rich social commentary and complex character development. I can't believe I waited so long before reading it!
