Today at Comic-Con International: San Diego, DC Entertainment announced the sequel to Batman Eternal, titled Batman and Robin Eternal.

Writers Scott Snyder and James Tynion IV will return to the series, with assists from Tom King, Tim Seeley, Jackson Lanzing, Ed Brisson and more. Tony Daniel will serve as the main artist on the book.

Snyder called Batman and Robin Eternal “larger than the first one: globe-spanning, bigger secrets,” and said that it “honors the legacy of Robin and also brings a new angle to it and makes something very fresh.”

A 26-issue, weekly series, Batman and Robin Eternal will celebrate the 75th anniversary of Robin by centering heavily on the legacy of the character...

...but it will also feature the long-awaited return of onetime Batgirl Cassandra Cain.

"This series is going to reintroduce Cassandra Cain to the DC Universe," returning co-writer James Tynion IV told reporters this morning. "We can’t talk too much about that just yet but this is a character that for me at least I have loved for my entire comic-reading life. The fact that we have the opportunity to bring her back in a very, very central role — she is on of the three leads of this story, her, Dick and Harper Rowe — I’m really pumped.”

Batman and Robin Eternal launches in October.
