Irrational Games' upcoming game BioShock Infinite is a little hard to wrap your mind around, even starting with its setting. What's up with that floating city? Who lives in that thing? Curious minds can have some of those questions answered thanks to an e-book prequel.

The book, BioShock Infinite: Mind in Revolt, is written by Irrational writer Joe Fielder, with guidance from Ken Levine.

“Since we first announced BioShock Infinite, our fans have asked for more information about Columbia and the complex cast of characters that inhabit the floating city,” said Fielder. “After reading the e-book, players will have a better understanding of BioShock Infinite’s world, the struggle between its factions, and the motivations of key characters, like rebel leader Daisy Fitzroy, without spoiling the mysteries of BioShock Infinite.”

It will be available on the Amazon Kindle on February 12 for $2.99. If you preorder the game from Amazon, you'll get it at no additional cost. Irrational is also reminding fans that if they preorder the game at participating retailers, they'll get the special Industrial Revolution Pack. The bonus includes three pieces of gear, 500 bonus currency, five lockpicks, and access to the Facebook game.

Look for the game on March 26.
