You Alright Boyo? (Bioshock)

After the death of Fontaine and the end of his brief reign over Rapture, Jack gave Tenenbaum, and the Little Sisters he saved, a submarine up to the surface so they could live their lives. However, he chose to stay in Rapture, in order to save the remaining Little Sisters and be the last good person in Rapture. But when he finds a certain Irishman that had been held hostage during one of his battles with the remaining supporters of Fontaine, he may realise that he isn't the last good person in all of Rapture.

A/N: This is an alternate universe, in which Atlas was not a persona developed by Fontaine, but an actual person and revolutionary leader, who was captured and replaced by Fontaine. The book is going to be from Jack's perspective, and the book will be in first person. There will be eventual Jatlas (Jack x Atlas), which means there's going to be gayness. If you don't like that, then don't read this book.
