Quarantine, by Greg Egan

  A pretty interesting idea, playing quantum mechanics and the idea of superposition collapse applied to the whole human race. Quarantine is short, but dense, it requires attention to understand the characters and the heavy scientific ideas. I wish it wasn't yet another private eye kind of setup, but it's a good book.

  I have been planning to read some more Egan for decades, so I am glad I did. I do feel that I may have read this book in the past, but it was before I started recording what I read and I didn't remember anything specific anyway. It's a very idea heavy book, though, like most Greg Egan stuff. I liked the book, but I didn't read it as carefully as I should have in order to really enjoy it.

  If you like your hard science cyberpunky sci-fi, this is for you.
