Irrational Games, developer of the first-person shooter BioShock Infinite, is releasing a "prequel" eBook for the title on Amazon Kindle in February.

BioShock Infinite: Mind in Revolt is written by Irrational Games' Joe Fielder and relates to events in the war-torn airborne city of Columbia before the arrival of Infinite star Booker DeWitt.

"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," Fielder told Eurogamer.

"After reading the eBook, 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."

The eBook is set seven years before the game, as players follow Vox Populi rebel Daisy Fitzroy following her capture by the Founders, the rulers of the sky city of Columbia. She is then used as a test subject by a psychologist studying the roots of rebellion and how to "cure" it. Mind in Revolt is written to resemble a publication from 1900s-era Columbia, including transcriptions, private diary entries and interviews, much like the actual game.

However, the book hasn't been without its controversy. Irrational Games' boss Kevin Levine has told Official PlayStation Magazine UK that the story was altered after "conversations with religious people on the team."

"What I said to them was, 'I'm not going to change anything to get your approval, but I think I understand what you're saying and I think I can do something that's going to make the story better, based on what you said,'" explained Levine.

"So I did that, and I'm grateful for them bringing in their perspective. The last thing I wanted to do was change something because it offends somebody, but the thing they pointed out was making it a lesser story."

The book is available for preorder on Amazon Kindle with a release date of Feb. 12. Those who preorder the BioShock Infinite game will receive this tie-in for free, while the rest will have to pay $2.99.
