Here's a description of Particle Horizon:

From the blood and dust of New Jerusalem, the Legion of the LightBringer wages a galactic war against those who would replace their god. Now, the time has come for the Union of Free Worlds to make a stand. The front line is the idyllic asteroid world of Angelhaven, where the greatest mind in human history has discovered an elemental power with far-reaching implications. A power that both sides will do anything to harness.

Marine commander Gomes leads the crack Union task force. An unrelenting warrior driven by revenge and a need for answers, he hides a strange ability neither science nor religion can explain.On the other side of the war, Aja is forced to fight for a cause she doesn’t believe in to protect her own secret.

Caught between them is Una, a living machine who battles for her humanity as her world falls apart.

Outnumbered ten to one and stalked by a mysterious nemesis, all three will play a role in unraveling Angelhaven’s enigma.

As the Legion invasion begins, unknown eyes watch with interest...


Before I write anything else, I'll mention that Selso Xisto's Particle Horizon was a pleasant surprise and an enjoyable reading experience, because it's a fresh and entertaining science fiction book.

Here's a bit of information about Particle Horizon:

The events take place in the distant future where humankind's technologial and scientific skills have advanced further than anybody can imagine. Humankind has the ability to inhabit asterdois, build sentient artificial intelligences, make genetic manipulations and modify plants genetically etc. As anybody can imagine, these advancements are great, but they also come with a price (humankind's future is threatened and almost anything could happen) and an important question hangs in the air... Has humankind finally gone too far?

Particle Horizon starts with a bang. In the first chapter the author tells how the asteroid world of Angelhaven is under attack and how a small group of people tries to stop the invaders. This is an interesting start, because it shows how bad the situation is for Angelhaven. This is, of course, only the beginning. Soon the reader will find out that there two different factions (Union of Free Worlds and the Legion of the LightBringer) and a war is going on. The Legion of the Lightbringer is considered to be a dangerous religious cult. The reader will also find out that one man has discovered a power which could be extremely dangerous in wrong hands. And while all these things are happening, something is watching humankind and its actions...

The asteroid world of Angelhaven is an interesting and fascinating place, because the author makes it come to life with his sentences. His descriptions of the different places and the happenings are vivid. It's interesting to read how people live in Angelhaven and how people glide and play in the tube where there's no gravity.

Here's some information about certain characters:

  • Una is a sentient living machine who is almost exactly like a human being. Her father is an intelligent man, Dr. Baghdasarian, who found the Chaos Pattern.
  • Aja is a soldier of the LightBringer Legion, but she has hew own secrets to protect. She is forced to fight against her will.
  • Gomes is a commander he's driven by the need for revenge. He has something to hide, because he doesn't want other people to know about his ability. He works for the Union of Free Worlds.

I like Selso Xisto's characters, because they're believable and interesting characters. Each character has his/her own problems and their actions are based on their feelings etc, so the author has spent time on creating good characters. Considering that Particle Horizon is Selso Xisto's debut book, the characters are surprisingly well developed.

I was positively impressed by Selso Xisto's writing style and ability to create a detailed story. There are plenty of debut science fiction books, which contain poor writing, but in my opinion this book is an exception. This book is surprisingly rich in content and the writing is good. The author writes about the happenings in an interesting way and makes the reader want to know how the story ends.

Selso Xisto writes fluently about technological wonders, religious zealotry, artificial intelligences and humankind's possible threats. The author shows well how the cult wages a religious war against people who use technology, but at the same time uses technology to defeat its enemies, which makes the cult's actions and purposes questionable. He also has a talent for keeping the story afloat on several levels from character development to world-building - this is a good achievement for a debut author. He has a creative imagination and a desire to tell stories.

I think it's good to mention that Particle Horizon is an easily accessible book, because it doesn't contain too much scientific vocabulary. There are lots of science fiction books, which aren't exactly suitable for readers who read mostly mainstream fiction. These mainstream readers often tend to avoid science fiction, because science fiction may contain too much scientific information etc, but this book is totally different. This book contains certain important terms etc, because the events takes place in space, but the amount of information isn't overwhelming, so mainstream readers will be able to enjoy this book. The fast-paced action will please several readers.

I'll also mention that although Particle Horizon is a book for adults, it's possible that young adult readers may also enjoy reading it.

Particle Horizon is a surprisingly entertaining, well written and fast-paced science fiction book. I'm sure that readers, who aren't used to reading to science fiction, will be delighted to read this book, because the plot moves fast forward and the characters are interesting. I think that experienced readers will also enjoy this book, because the story is entertaining.

Good and harmless entertainment!
