Pandora's Star is the book where Peter F. Hamilton first introduces readers to the human Commonwealth. It is the year 2380 and humanity has populated several hundred worlds across hundreds of light years, all due to wormhole technology. That is when a single astronomer observes something unexplainable about 1000 light years from Earth - two stars just disappear when they become simultaneously enclosed by some kind of structure. This sparks all kinds of debate within the Commonwealth as whoever did this must haves technology far superior to humanity and could pose a serious threat to the Commonwealth despite the distance. What to do about it? Sit back and do nothing hoping to avoid detection by these superior aliens or attempt to find a way to traverse the massive distance to take a closer look? Neither option is a great one and the Commonwealth's ultimate decision makes up the core of this interesting story.
