You can get a very popular book for a really, really low price on Google Play today. And by low price, I mean it's totally free. The book, which inspired the movie, is number two of the three-part series by Suzanne Collins that follows Katniss Everdeen's adventure in the dystopic future.

Normally, the book is $12.99. The first and third books are also marked down to $8.57 and $6.50, respectively. Giving away the second book is kind of clever, since it is not all that useful without also getting the first book. And, if you get the first and the second, you're not just going to ignore the third book.

There's no indication of how long this deal will last, so you'll want to grab it while you can.
