Figured I'd make a post that's easily identifiable to get Overdrive.
Use this link to get the latest version of Overdrive for the Android OS, straight from the source:

If you want to use it as an alternative to ADE on your Windows/Mac machine, get it here:

And in case you're not sure why you require overdrive; Overdrive is used to view DRM'd Epub books, PDF books and MP3 Audio books(WMA not currently supported in this version of Overdrive). Libraries commonly used this software to lend out their books, but it should work with any other Adobe DRM'd media as well (ie: epub versions of books downloaded from KOBO). Even if you decide not to use ADE (Adobe Digital Edition), you still require an Adobe ID to decrypt DRM'd media. You can get an Adobe ID by going to
www.adobe.com and creating an account with them.
