Brave Old World #1

Synopsis

When the computer glitch everyone feared instead causes time itself to flip back to the year 1900, it's up to a band of elite computer programmers to reinvent the technology of the digital age in a barely industrial America. Their plan is to hack their way back into the 21st century by creating a bug-free computer age, but other issues, such as survival, take precedence when aliens from an alternate, dystopian year 2000 (a timeline created by the team's activities in 1900) travel back in time with orders to kill.
