Nominated for a Hugo and a Nebula, this is award-winning science fiction. That said, I wouldn’t recommend it to my casual reading friends. While I’ve enjoyed other works in the subgenre of Military Sci-Fi, this one was too fragmentary and confusing for many outsiders or infrequent sci-fi readers to really grok.
Other reviewers have commented how that “confusion” is a good thing, that the total immersion into an alien mindset geared around consensus reality would be a confusing thing indeed and that this it is therefore an accurate portrayal. I think that’s a bit of insider baseball. If you’ve read a lot of science fiction, I could see how this would resonate (it’s new, it’s different!), but there are so many good books, this just wouldn’t make my recommended reading list.
