Final Days

A Science Fiction book by Gary Gibson.

Using artificially created wormholes, humanity has begun its first steps towards colonizing the galaxy. So far, all signs says that Humanity is alone. Or at least that was the theory until another wormhole network was discovered. People are sent to investigate, and bring back any advanced technology.

However, using a quirk in how the wormholes also sends the person through time, people soon discover a future Earth seemingly dead and covered in great plant shaped metal objects. The race is on to find a way to save the planet.

 * Casual Interstellar Travel
 * Justified, lampshaded and in one case played straight. Because of the wormholes, most of your travel efforts will be getting to the gate. When Saul needs to get back to Earth from Newton he mentions that despite travelling millions of kilometres, it felt like three and a half kilometres for him. Three of these were spent walking to the array housing the wormholes, and another five hundred meters walking around the departure and arrival halls.

 * Also, the Pykrete guns. Why would anyone make guns that shoot pykrete bullets when normals bullets are just as good? No idea, but it's a neat trick.
 * Time Travel – A side effect of travelling through the wormholes is that you also travel through time. Subjectively, this is not a big deal, as it is easy to stay in touch with Earth and the colonies. But the first chapter takes place 1x10^14 years into the future. At this point all the stars in the night sky have gone cold.
 * You Can't Fight Fate – Several characters note that because they have already observed the Earth being destroyed, they can't change that outcome.
