Thanks for the tip - I'm happy to see more "spin-off" novels like that, so I'll look forward to it. However, I don't like Baen's EARC policy
: they charge extra money for something that probably has mistakes, they explicitly tell you not to report any mistakes, and then you have to buy the final release all over again.
By contrast, I think Microsoft Press have handled it much better with one of their new books (Programming Windows
): you pay a fee, then you get the preview copy and all updates, including the final release version. The price starts out quite low ($10), then gradually increases as they get closer to the release date, presumably because the quality of the content will improve.
