**This review contains spoilers!**
Ya know, I've really got to start reviewing more books that I loathed with a passion so that I can't be accused of just handing out five stars to every novel I ever picked up. Yet "Marooned in Realtime" has earned every accolade I could give it. Most books fade rapidly from my memory, providing a passing diversion at best. This one is deep, moving, wrenching, thought-provoking, tragic. If I could only keep, say, ten books, this would be one of them.
Vernor Vinge picks up on the milieu he created in an earlier book and expands upon the use of "bobble" technology. The bobbles are stasis bubbles that can be set for durations ranging from hours to centuries. Since nothing inside them experiences the flow of time, they can be used as a kind of one-way time travel ticket to the future. Simply set the parameters as desired, pop up a bobble around you, and see what the world's like in two centuries.
This is what a group of men and women are doing on a deserted future Earth, slowly making their way up the timestream to see what lies ahead, and hoping to come back into synch with the rest of scattered humanity. Vinge does a good job of introducing and developing characters, making you identify with or understand them. The key figure is from close to our time and acts as our point of view.
He is the one that has to investigate what could only be a murder, when the group bobbles up for another leap and one of their members is left behind. For the others, only an instant passes; for the stranded woman, years of isolation and loneliness go by, with her only hope being to live long enough for the bobble to dissipate and provide her salvation and succor. And...she doesn't make it. She spends months struggling in fear and grief, an arm's length and an eternity away from her friends inside the mirrored bobble, hoping, praying.
The tale of her struggle, told in a sort of flashback as the lawman reads her journals, is the heart of the book and is truly heartbreaking. Even knowing that she didn't survive, you find yourself hoping, as you read along with the investigator, that somehow it will all turn out all right. But it won't.
"Marooned in Realtime" is a minor and overlooked classic by an author who creates rich, vivid, intricately detailed worlds and characters and who excels in exploring the ramifications of advanced technology and social innovations. Vinge only bangs out a book about every three years or so, but they are well worth the wait. This is the best of them; give it a try, and you won't regret it.
