The creator-owned miniseries, written by Ed Brisson and illustrated by Michael Walsh, will debut through the publisher and Shadowline in November.
Slated to run for five issues, Comeback centres on a secret organisation called Reconnect, which sends agents back in time to rescue people before their untimely deaths.
The comic's protagonist is an agent named Mark, who soon discovers that there is a dark side to preventing death.
"Mark does this job because it's fairly easy and pays well. Although it's illegal, he justifies it to himself because he's helping people," said Brisson.
"He's pushed to do some things that go counter to his own beliefs and is stuck with the moral dilemma of breaking his own code of ethics or dying."
Comeback #1 will be released on November 21.
