The application is free, but the books themselves must be purchased through Amazon via mobile Safari or from a PC or Mac and then synced over. Most of the books cost $9.99 and you can sample the first chapter for free before purchasing.
Any book purchased for the Kindle can be transferred over to the iPhone/iPod Touch for free and "WhisperSync" is enabled to allow flawless transitions from a Kindle device to your iPhone if you were currently reading a book on one of the devices and want to switch during.
