Baen Books is running a special promotion that lets beta testers for online gamers win free eBooks.  Internet users who sign up to play Plant Baen, the publisher’s social game, will receive a free eBook. Players can earn additional eBooks if they do well in the game.

Here is more about the game from Planet Baen’s Facebook page: “The object of the game is to found a settlement on a lawless planet on the galactic frontier. The OTHER object of the game is to earn free Baen Ebooks by playing. We, of course, hope a player will stop playing, read and enjoy the book, buy all the other books in a series, then come back to the game and play some more. And for developing writers out there, we have a short story anthology that will be linked to the game, Stories from the Bars of Planet Baen.”

You don’t have to be a Facebook user to play the game, but it does make it easier to receive gifts. The promotion already has readers talking. On Facebook user wrote: “I don’t play FB games…wait…what? Free E-books? OK.”
