This book started off with a really interesting premise for the first book. It was fast-paced and described the world in great detail. As the books progressed, however, they got progressively more dull and the worlds were not described as well so the reader cannot get a sense of plot or cohesiveness between the books. The heroes and heroines are a mixed bag: while Steve Ryland, Donna Creery, Quarla Snow, and Cliff Hawk make complex, or at least truly heroic characters, Boise Gann, Andy Quam, and Molly Zaldivar are boring and not complex at all, and this is how the last book loses steam. If you are considering purchasing these as separate volumes, I would recommend just getting the first two, because I feel the story would have done better to leave off at Starchild rather than go into Rogue Star, which, as I said earlier, was boring.
