Sync my Kindle books

To download content from Manage your Kindle:

1. Visit Manage your Kindle.
2. Click the Actions button next to the title you want to download.
3. Select "Deliver to my" from the dropdown menu and select your iPad, iPhone or iPod touch.

Note: If your device does not appear in the "Deliver to" pull-down menu, you need to register your device.

If your iPad, iPhone or iPod touch is connected to a network, your book will download and appear on the Home screen the next time you open or sync the Kindle application. You may be prompted to log into your Amazon.com account if you haven't already.

They won't. Your kindle books should be on your Amazon account - if you want to have copies of them on your computer then you could download the Kindle for PC/Mac program and download your books from Amazon into that

Not sure - I don't have Kindle on my Mac, but possibly not, now that you ask. I don't know how often Amazon remove books from their site and therefore how likely it is that you won't be able to re-download them from Amazon in the future.

You can always re-download your Kindle books directly from Amazon.
