I created ePub and MOBI e-books using the save as mechanism. Everything is fine except when I open the book the first time using a Kindle or go to 'Beginning' on the Kindle it goes to the middle of a section. How do I mark the 'Beginning' within a book? Or what determines the beginning?

'Beginning' in MOBI e-Book is in middle of chapter
Please, have a look at Converting to Kindle in the Atlantis online help:

Now, if you’re not happy with the location Atlantis automatically chose as the beginning of your eBook, you need to bookmark a different location in your source document as its "beginning". For this, click the target location within the source document, then press the “Shift+Alt+B” hot key, type "start" (without quotes), and click the "OK" button:When a Kindle eBook is created through Atlantis, the first chapter of the eBook is automatically marked as its "Beginning". And the "Go to... > Beginning" command of the Kindle will bring you to the first chapter of the eBook.
