In A Fire Upon the Deep, A colony of humans sets up in the transcendence, the part of the galaxy where computers work so well AI can ascend and become godlike. The humans start tinkering with an old artifact, and naturally, they awaken an ancient power. The reborn AI sets off on a reign of destruction, and soon is killing even other deities. 

A single ship escapes with the secret to save the universe and jets off through the beyond to the very edge of the slowness, the sector of the galaxy where the speed of light is an immutable law and computers don’t work very well. It crash lands there on a primitive, medieval world populated by doglike aliens called Tines, and two children are the only survivors of the crash. 

Meanwhile, in the wider world, the race is on to reach the crashed ship. Two humans and two tree-like aliens called Scroderiders are alone, pursued by the agents of the death god, trying to reach the kids and save the galaxy. 

This is a book that is full of big, interesting ideas that are seamlessly woven into an incredibly entertaining story - it will absolutely keep you turning the pages and staying up too late reading.

Hyperion by Dan Simmons is one of the best sci fi books of all time, and won the Hugo and the Locus awards in 1990. We give it a 4.5 / 5. 

The book is a space epic in the form of Chaucer’s Canterbury tales. Hyperion is a colony world at the edge of Hegemony space, and home to some of the greatest mysteries of the galaxy. A network of giant labyrinths crisscrosses underground across the whole planet, the Time Tombs are surrounded by an anti-entropic field that makes time run backwards, and a fearsome, three-meter-tall metal monster with truly terrifying superpowers called the Shrike that emerges periodically to murder innocent passerby. 

7 pilgrims travel to Hyperion from humanity’s various portal-connected “web worlds” to return to the strange planet in advance of an alien invasion. Like in Chaucer, the story largely consists of each pilgrims’ self-narrated back story, intercut with their return journey to Hyperion and hence, the Time Tombs. The book is a masterful mashup of both real-world literary history and science fiction tropes. The form of the novel engages you deeply in the overall mystery, and some of the pilgrim's stories will stick with you for years to come. 

As always, we also recommend a few similar books to check out if you loved Hyperion: 

Sirens of Titan by Vonnegut 

Fire Upon the Deep by Vernor Vinge 

Ancillary Justice by Anne Leckie

This series is beloved by its fans, but doesn't get enough recognition in the wider world. These are incredible, character-driven stories that are a breeze to read but beneath the surface have so much to say about what's most important in life and the meaning and definition of personal identity. That makes them the perfect intro to sci fi for anyone new to the genre, and a refreshing read for any longtime sci fi fan. 4.25 / 5 stars.

The Vorkosigan Saga is a series of 16 books by Lois McMaster Bujold, three of which won the Hugo award in 1991, 1992, and  1995. The Vor Game, Barrayar, Mirror Dance, and the rest of the saga follow the members of the Vorkosigan family, one of the feudal ruling families on the planet Barrayar. The books are digestible and concise by sci fi standards (350-600 pages, 11-18 hours of audiobook). The series is also loosely episodic, so you don't have to read them in order.

These are character-driven stories, and you're sure to remember these characters for years. The most important of them, Miles Vorkosigan, is clearly the inspiration for George R.R. Martin's Tyrion Lannister, and is even more likable than the knock-off Lannister version. He's a dwarf who suffers from several physical disabilities, but he's wildly brilliant, funny, and imperious, and is constantly throwing himself into danger to protect his friends and family (or just get himself out of a jam of his own making).

Across the generations, the Vorkosigan family are the main advisers to generations of Barrayaran emperors, and have to use their wits and intellect to get the empire out of trouble and slowly push Barrayaran society out of its backward nature. These are books about people, the stories that make them who they are, and how they create and define their identities in an unfriendly universe.

A Canticle for Leibowitz is set in the aftermath of a horrible nuclear war. The survivors blamed science, and killed intellectuals and burned all the books they could get their hands on. A monastery in the desert of the western US is one of the few places on earth to preserve any knowledge, and the book follows the monks of the monastery in three sections over the following thousand years.

The monks are witty, wry, and funny as hell, and they make the book into an incredibly fun read.

It's an amazing exploration of the nature of knowledge and religion. The book is also an incredible window in the late 50s and early 60s, when nuclear weapons felt very real and we had to begin to come to terms with the horrible weapons we'd invented. That's two for the price of one folks - spend some time in the nuclear wasteland, and spend some time in 1959 too.

And, as always, a few related books we love that we recommend: The Name of the Rose by Umberto Eco, The Forever War by Joe Haldeman, The Hitchhiker’s Guide to the Galaxy by Douglas Adams, and Stranger in a Strange Land by Robert Heinlein (and Heinlein's Double Star too for good measure).

This is a no-spoiler review. In advance of the new Dune movie, we thought it would be fun to revisit Dune and remember what made it great (and the things that aren't so great).

The names are incredible - who can forget the Fremen, the Gom Jabbar, or the Reverend Mother? The writing, on the other hand - we wish we could forget the constant repetition, horrific dialogue, and ending that comes so fast it's over before you know it was even really happening.

If you haven't the read Dune and want to decide whether to read it - this one's for you. Or, if you want to dig back into the book without re-reading the whole thing - this one's for you too.

And, if you like Dune, we also recommend a few related books at the end of the episode: The Void Trilogy, Ender's Game, and The Vorkosigan Saga.
