Currents is Google's attempt to bring a Flipbook-like experience to Android, and for the most part, it does a good job.
All your news sources are displayed in your Currents library, and you can easily customize what shows up in your library by going into the settings menu and searching for new sources to subscribe to. Each website in your library will display as a small square with that website's logo inside. Tapping on one of these squares will open a virtual magazine of that website's most recent stories. Depending on the website, each "magazine" will be formatted differently--but for the most part, all of them feature a large "cover story" that will appear prominently when you first enter that magazine.
Aside from your library of websites, Google Currents also has a separate tab that shows you what's hot on Google News, which can be helpful for keeping on top of world events. Although it received some less-than-enthusiastic reviews at first, Google Currents continues to improve with each update, and is worth taking a look at if you are a fan of apps like Flipbook or Zite on iOS.
