It seems every writer of science fiction has to publish at least one novel set in the not-too-distant future, in which the Earth has been largely destroyed by wars or environmental disasters, currently commonplace amenities such as electricity and personal freedom are rare, and the future is just as hopeless as the present. "Pirates of the Universe" is typical of that sub-genre. The main character begins in a position of status that insulates him from the difficulties of his world. His privileges are stripped from him without explanation, and he embarks on a journey to discover unexpected truths about his family, his society, and the universe.
There are positive aspects of this book that set it apart from most other works of its type. The plot is uncommonly complex, and there are a number of unusual, interesting details - it's clear that Bisson has devoted a lot of thought to the world he's created, and it makes for an engaging and stimulating read. But these strengths are marred by the book's essential weakness, which is - not surprisingly - its post-apocalyptic setting and tone. Bisson is often preoccupied by impressing upon his readers the unpleasantness of the book's universe, and this makes the book awkward and unpleasant to read at times.
Overall, "Pirates of the Universe" is an interesting and enjoyable book. The author has some good ideas, and he has the ability to write a plot that strings them together engagingly. However, readers who can't tolerate the preachiness that seems inherent to the genre will probably not want to subject themselves to the dose Bisson metes out.
