Incandescence

By: Greg Egan

Narrated by: Paul Boehmer

Hugo Award-winning author Egan returns to the field with Incandescence, a novel of hard SF.

The Amalgam spans nearly the entire galaxy, and is composed of innumerable beings from a wild variety of races, some human or near it, some entirely other. The one place that they cannot go is the bulge, the bright, hot center of the galaxy. There dwell the Aloof, who for millions of years have deflected any and all attempts to communicate with or visit them. So when Rakesh is offered an opportunity to travel within their sphere, in search of a lost race, he cannot turn it down.

Roi is a member of that lost race, which is not only lost to the Amalgam, but lost to itself. In their world, there is but toil, and history and science are luxuries that they can ill afford. Rakesh's journey will take him across millennia and light years. Roi's will take her across vistas of learning and discovery just as vast.

Critic reviews

"The driving forces of this novel are a pure scientific puzzle and the intellectual joy of finding answers.... Those who like their science hard will appreciate his thorough research and intricate speculations." (Booklist)

It is dense

So much to love here; technology developing so far that human decadence is a way of life, aliens being really really alien, separate stories that end up colliding in unexpected ways. It's all good but it is really dense

Two hard SF tales of outer & inner space

The POV’s of the two alternating narratives that comprise this novel are so wildly different in style, that it feels like two separate authors are at work. One follows a restless citizen of a far future galactic civilization on a quest to discover something, anything, new and mysterious in the aseptically tame society he inhabits. The other narrative observes an alien species in an environment wildly different than our own discovering fundamental physics on their own terms under the threat of environmental disaster. Of the two, I must say I preferred the space opera former to the ‘rock opera’ latter because it offered a broader cosmic scope in dimension and more wonder. As others have noted, the alien (‘ark dweller’) storyline is incredibly thick with mathematical exposition. None of it was deep enough to completely suffocate me, but it did begin to feel like an algebraic overdose sometime in the first half of the book with the majority of it still to come. Hand in hand with the descriptions of ratios of weight measurements to angles in space-time, however, is a truly engaging story with high stakes drama and interesting alien biology and thought modes. It just wasn’t as thought-provoking for me as Rakesh the post-human’s star system-hopping and at-will body redesigning pursuit. In this half of the book, Egan’s hard SF soars like the space opera I expected, filled with concepts like mind uploads transmitted between stars to be reassembled by nano-machine, and lifetimes spent shifting between digital environments and corporeal ones over the course of millennia.

Another great piece by Greg Egan

If you want some sci-fi with heavy emphasis on scientific aspect - look no further.

Incandescence – Science / fiction

This is hard core science fiction with the science part underlined. There were times during the story when I felt I was in an advanced Physics class listening to a lecture on Orbital Mechanics; but the overall experience was entertaining and should excite the hardcore science fiction fan.
Set in the far distant future where DNA based life forms (humans) have advanced and can now freely travel across the known universe with the exception of its galactic core which is inhabited by a species that prefer isolation and are appropriately called the “Aloof,” the story is separated into two separate plot lines which are told alternately throughout the book. In our first plot line DNA is discovered in part of the Universe controlled by the Aloof and it sends a couple to seek out its source. We learn about an insect-like species that are trying to come to grips with their relativity in the second. These two plot lines seem destined to come together in the end, but they never really do.
Overall I found Greg Egan’s descriptions of a galaxy-spanning, post human civilization fascinating and the narrator, Paul Boehmer, gives a good performance.

Read it instead

Is there anything you would change about this book?

This is a book I would read instead but have not yet. I like Greg Egan, he's one of my top authors. But this book borrowed much from physics and needed diagrams. I couldn't think or follow at the speed of an audio book narrator. I imagine if I had book in hand, I would read certain parts numerous times in order to "get it".

Not the narrators fault, the book merely doesn't lend itself to the audible medium.
