The book looks great!

Thanks!

A bunch of inter-book links such as ...

D'oh. It's all good in the epub, but something broke (for very dumb reasons) converting the mobi. It's fixed now. If you've already bought the book though Amazon or e-junkie, you'll have to re-download the file to get the fixed one (in a few hours, while Amazon approves the new book). Sorry about that.

The difference between a link going to the web and one going to a location within the book aren't obvious: one is only a slighter darker grey than the other. In Calibri the links are a nice green/blue, but my kindle doesn't have colours.

Not much we can do about this. Amazon is very restrictive in how you can modify the styling of links. It works fine for displays with color, but people with e-ink displays are out of luck. :-(

Thanks.
