9 lightyears per second
I've read ebooks on a lot of different web sites and the one thing that all of them have in common is that no effort is ever made to police their authors. Authors of ongoing books (I.e., novels not yet completed) are allowed to publish at their own pace ignoring the commitments made to their readers. Professionals meet their commitments and their bosses take appropriate actions when they don't. That is why I will never again start reading a book that has not yet been completed. Unfortunately, I only discovered this rampent lack of professionalism after I started reading this book.
