Thanks for your help. The book is now for sale (buy it here:
http://www.amazon.com/Reflections-Or...dp/B00NE641WU/ ... or not) but if you use the "LOOK INSIDE" feature, you'll see that the formatting is all screwed up -- just like it was when I sent it to iOS via SEND.
As I say, the book is fine in an actual Kindle...!
What's going on?
