I won't mention too much about the actual stories - suffice to say that I've really enjoyed them. Compelling, well written, touching (in a few cases) and thought provoking. A welcome dose of intelligent sci-fi.
However, the reading experience has been significantly lessened by what is all too common on the Kindle - the quality of the text and layout. Unlike older books that were presumably scanned and OCR'd (and thus suffer from typos and odd formatting), Zima Blue can't possibly use age as an excuse. Yet somehow, every single page is inflicted with a spacing issue between paragraphs - in short, there is an extra blank line in between each paragraph. It may not sound like much, but in sections where there is a lot of dialogue, you lose half the content on the page. And it is impossible to tell where section breaks occur, severely disrupting reading flow.
Come on Amazon! If you're going to sell e-books for the same price as the paperback version, at least have the common decency to make the experience the same!
