Want an ebook reader app that syncs your progress in cloud and across your android devices? I wanted something like this for months and finally found it! It is called Fabrik and it is fantastic. You put your ebooks in dropbox, then connect the app to dropbox and you're done. I've been using it for a few weeks and have no complaints. I can recommend to everyone who can't use services meant for americans.
There are two versions. Free and Pro (pro is ~$3). Free shows adds (after a few days of use) in the menus but not while you read. The app is new and not as customizeable as many other readers, but the dev is active and adds stuff regularly.
Here is the link to the free version:
