Nigel Sheldon, the long-lived engineer responsible for the technology of the interstellar Commonwealth, is dispatched on a mission to the Void, a giant black hole-like artefact that is expanding and may threaten the galaxy. With the help of the alien Raiel he enters the void seeking the planet Querencia, but instead finds himself on a different planet Bienvenido where the descendants of a starship previously drawn into the Void have fought for thousands of years against the sinister Fallers.
As you can see it's hard to describe The Abyss Beyond Dreams in short sentences. This is a Peter F. Hamilton novel and as such it's of epic proportions - I can barely lift my Kindle. A novel of this length is a challenge to write or to read - it cannot be indulgent. There must be depth and complexity that justify the length, but it must maintain quality and the relationship with the reader throughout.
The Abyss rises to this challenge through the story of Bienvenido which is told through several viewpoints - the original colonists, their descendants thousands of years later, and Nigel Sheldon and his allies. It's a story of individuals living through and driving societal change in a time of revolution - not unlike Victor Hugo's novel Les Miserables. There are a few differences - Hugo dwells less on the flesh-eating alien mimics, for instance, but there are a lot of common themes too. I don't know if the endings are similar as reading Les Miserables proved to be like swimming through the overlong backstory for treacle. I can't help thinking that that novel would be much better if 95% of the plot were removed and the remaining few words were set to music... but I digress.
The plot of The Abyss is sufficiently complex and multi-layered. At its centre is a revolution which is not what it seems. The constant enemy, the Fallers, are also a good horror creation with their own mystery, although I did wonder why they only appear to have started their invasion when the humans arrived - by rights they should have already have established themselves and been ready with a welcoming party. Sheldon is an interesting character - deeply moral but willing to consider inhuman, terrible acts in order to achieve a greater end, he is the logical product of his long life and his ability to see the bigger picture.
The Abyss is part of a two-novel series set in parallel to the events of the Void Trilogy, many years later than the Commonwealth Saga novels. I previously reviewed The Dreaming Void here and my thoughts about novel length can be found here. These novels are all set in the Commonwealth, a civilisation like Iain M. Banks' Culture in some ways - citizens are biologically and technologically enhanced, interstellar travel and artificial intelligence are commonplace and society is organized around a very, very long life expectancy. Unlike the Culture, the Commonwealth is a continuation of Earth history and is primarily human-led. I enjoyed this return to the universe of the Commonwealth and look forward to the sequel Night Without Stars.
