I can see how it wouldn't be for everyone.
One weird thing about reading ebook versions is in not always aware of how long they are, at least at the start. With PSS, I was thinking it strange that so little happened, then I realized that, even though I was a couple hundred pages in, I was less than a third of the way through.
An IRL friend who's very into SF also recently recommended The City And The City, so I'll probably read it soon.
