I object to this being classified as science fiction. I get that there's a science-y fictional device in it, but that isn't what the story is about. It's not even a story. It's a series of vignettes centering around the device and one could argue, to a vague degree, around one person.

If you like the kind of book that basically provides a series of short stories about tangentially related characters, then you'll enjoy this book. It was interesting, clever, and quite well written.

However, I don't like these kind of books, and I feel like I was tricked into reading it because it was classified as science fiction. It's not. It's just plain old, make you think about your life, well written, fiction...and that's not what I like to read.
