Originally published in two parts, Orphans of the Sky is a brilliant treatment of the concept of a multi-generational interstellar voyage (or "generation ship"). Or, at least the first half is.
In the first part, "Universe," we meet a mostly agrarian society living in the lower decks of The Ship. The civilized Crew (led by the elite Scientists and headed by the Captain) live in the lower (outer) decks where gravity is strongest; the upper (inner) decks are where where gravity is light and the Muties (mutant descendants of the original mutineers) rule.
This is a journey gone wrong...a mutiny shortly after take-off disrupted the ship's society, and after many generations, the crew has forgotten they live on a spaceship...they think of the Ship as being the whole of the Universe. A young scientist, Hugh, learns more when he is captured by the Muties.
"Universe" has been hailed as one of the best and most-important sci-fi novellas ever. It is the first instance of a "generation ship" concept, an idea which has been copied many times. I'm not a particular fan of Robert Heinlein, but this one is great.
I have less good things to say about "Common Sense," the second half of the book. Hugh, now armed with the truth and a cohort of brutal Muties tries to convince the Scientists and Crew about the true nature of the ship, and that they should steer it to its destination. "Universe" was a seminal, ground-breaking work. "Common Sense" finished up the story (if it needed finishing), but I find it particularly unsatisfying.
This is the second audiobook narrated by Eric Michael Summerer that I've heard, and he remains a capable and effective narrator.
God Emperor of Dune compares well with the original Dune, better than the previous two sequels (Dune Messiah and Children of Dune). It doesn't quite measure up to the standard of the first book, but few books, anywhere, do.
Warning: God Emperor of Dune is the third sequel to Dune. Ignore this book until you are familiar with Dune and the first 2 sequels.
It is 3500 years since Leto II Atreides donned his living sandtrout armor. Leto is now a living deity as well as galactic emperor...prescient, super-intelligent, supremely strong, vengeful...and more sandworm than man. Arrakis is now lush and green; the sandworms (except for Leto) are all but extinct. There is no more spice, excepting centuries-old stockpiles.
This is Leto's Golden Path...the future for humanity that he foresaw and planned 3500 years ago.
Like most of Herbert's Dune books, this book has an operatic feel...it moves slowly and most of the book is taken up with dialogue. The story really is the people, their motives and their schemes. This book revolves almost entirely around the title character (more so than the prior books), but, then, the God Emperor is the dominant story of this time and place.
The narration is very well done; Simon Vance narrates most of the book, with Katherine Kellgren reading the occasional female-dominated chapter and Scott Brick delivering the epigraphs at the start of each chapter. Three excellent readers who did a great job.
An excellent dystopian view of the future, "Make Room! Make Room!" shows a world that is depressingly believable...vastly overcrowded cities, failing infrastructure and the struggle to secure the basic necessities (especially water) dominate every-day life. The book is very prescient; it reflects current concerns over environmental destruction and exhaustion of natural resources, which seemed remote and hypothetical when the book was published in 1966 (only 4 years after "Silent Spring" started the environmental movement).
The novel is written as a police procedural set in the New York City of 1999. Making the protagonist a detective was effective as it allowed the reader to see many aspects of the "Make Room!" world in a natural manner. However, between the setting and the realities of police work, the book is very bleak.
The movie "Soylent Green" was loosely based on "Make Room! Make Room!" Very loosely. More accurately, the movie setting was taken from the book and some of the plot elements, but the story, the themes and the conclusion are very different. For example, there is no "soylent green" in the book at all. If you've seen the movie, you haven't read the book, or vice versa.
Those who want to study such things might want to compare "Make Room! Make Room!" to the more antiseptic future envisioned in "Brave New World" (which was written about 35 years earlier).
Summerer's narration is quite good. He really pulls the listener into the story, and his reading is well paced and the characters are voiced distinctly without much apparent strain on Summerer's part, or the listener's (it helps that there aren't really all that many characters).
In conclusion, an interesting, if depressing, listen.
