Ship Breaker by Paolo Bacigalupi.
An engaging story set in a well-realized universe. This novel is positioned as a young-adult book, but it doesn't underestimate its reader. 7.5 out of 10.
The Windup Girl by Paolo Bacigalupi.
The premise for this story, which is set in the same universe as Ship Breaker, but on the other side of the Earth, is compelling, and the worldbuilding is impressive. However, the characters weren't identifiable and the story was too slow. I just couldn't get into it and stopped about two thirds of the way in. 3.5 out of 10.
Hull Zero Three by Greg Bear.
The premise of this story is intriguing. Unfortunately, since the narrator and all the other characters have no idea of what's going on around them, the plot comes off as a muddled mess. 5.0 out of 10.
Rainbows End by Vernor Vinge.
This story is set in the same universe a Fast Times at Fairmont High, and it includes at least 5 of the same characters. Interestingly, 2 of the main characters are substantially revamped for this novel. The worldbuilding is typical of Vinge, which is to say impressive. The story is exciting, as well. 8.5 out of 10.
An interesting story set in the very near future. The main character is so likable that I didn't mind reading from the perspective of a teenage girl. Sadly, there's a bit too much teen-girl drama. 7.5 out of 10.
