 Every week this month I'm reviewing a science fiction novel series and this week It's the heritage universe by Charles Sheffield these stories take place several thousand years in the future when the human race and Seven or eight other space faring species who are not at war with each other Surprisingly have the common experience of finding the galaxy littered with vast Abandoned machines some the size of planets some even light years across who built them what they're supposed to do Nobody knows the action of the first book centers around two planets that are literally attached by an artificial tether And they are fast approaching a grand convergence with the double star They orbit and the gas giant that they share the system with experts from all over the galaxy are convinced that this means something If you're interested in the alien artifact type story, then obviously this is for you the writing style is very dry There's a fair number of characters and they are not at all interesting some of the text actually consists of excerpts from a Catalog describing the various giant artifacts and of course those are the most memorable parts There are two other books in the series that came years later, but I never got to those You can support 30 second sci-fi and my other projects by becoming a patron There's a link in the description below and visit the 30 second sci-fi tumbler.
