As long as your handset is Android 2.1 or later, you can get the app now and start downloading. A Books section has also been added to Android Market, to go along with the Apps and Games.
A statement from Google reads: "Readers in the UK now have access to the world's largest e-books collection, with hundreds of thousands of e-books for sale - from major UK publishers like Hachette, Random House and Penguin - as well as more than two million public domain e-books for free."
