Across Realtime
By Vernor Vinge

This is the omnibus edition containing the novels "The Peace War" and "Marooned in Realtime".

Warning: perhaps minor spoilers.

The Peace War

What price would you pay for peace? What would it cost you? And what about costs to society? These are some of the things Vinge considers in his 1984 novel "The Peace War".

In the book, peace is imposed through a "Peace Authority", a world-wide government that has a monopoly on a powerful weapon: a weapon that can enforce and isolate threats, small or large. Through this, they keep society at a "safer", lower level of technological sophistication. The USA and other sovereign states do not exist anymore.

The weapon is a "bobble": an impenetrable force-field bubble around a space (and it turns out, a time). This can be used to completely isolate and neutralise a threat, whether people or missiles.

There is a resistance of course: a mix of clans, tribes, gangs and technology devotees Vinge called "tinkerers": or tinkers. The novel describes how the ungoverned and tinkers fight back against the "Peacers". Vinge is obvious about where his sympathies lie but he give the Peace Authority its due as well.

I thought this was a great adventure novel. Exciting and full of good extrapolations of the new technologies coming online in the 1990's and early 2000's.

Marooned in Realtime

In the sequel, Vinge shows us a consequence of having such "bobbling" capability. The story is sets millions of years in the future: because (in effect) these things act as a one-way time machine. This book is a murder mystery story and quite different to the first novel. I found it just as enjoyable though.

Vinge, who died earlier this year, had an abiding interest in and sympathy with the quest for knowledge and scientific progress. A Professor of Maths and Computer Science at San Diego State University in California, in many ways he epitomised the Californian techno-optimism of the 1980's and 1990's. The era of the early internet, the birth of the Electronic Freedom Foundation and magazines like Wired (founded 1991). I definitely sympathised with this vision, and still do, even though it can seem naive today and has been overtaken by the reality of the modern world (and everything this entails). We are less optimistic about technology today, sadly.

Science-fiction is a great genre for exploring all the different ways science and technology can change the world, and ourselves. I like Vinge's books: this is the second time I've read these novels. I liked them before and this time I think I liked them even more. If you're in the right mood for a book then it makes all the difference. I am sure I'll come back to them in the future again.
