I really enjoyed the author's Heritage Universe series, so I thought I'd give this a try. Even though this was written in 1998, it reads like a 1950s YA novel. Although the scientific details are not outdated, nor are they tremendously exciting either. You can tell Charles Sheffield was into astronomy as he spends time on the color of a nebula and that he was a physicist as he explains ideas using graphs.It doesn't liven up the book however, and as the story revolves around the characters they come across mostly as just plain Joe from Kokomo types. The author tries to make them lifelike, but is only partly successful.This was a light read that could have been more entertaining. It might appeal to those into Robert Heinlein's early novels, but thrilled I was not.
