It only took one episode for Starz to be sure about Outlander.

The network announced today that it has picked up this time-traveling drama for a second, 13-episode season.

It will be based on Diana Gabaldon’s’s second Outlander novel, “Dragonfly in Amber.”

Said Starz CEO Chris Albrecht in confirming the news: 

The overwhelming support Outlander has received from the fans, viewers and critics made the decision for us to go ahead with the second book a very easy one. Diana Gabaldon has given us years of great drama.  

"With an incredible artist such as Ronald D. Moore at the helm and a cast as spectacular as this, we look forward to continue this spell-binding journey with Claire, Jamie, Frank, Brianna, Roger and everybody over the centuries."

Outlander Season 1 Episode 1 set a ratings record for the network and creator Ronald D. Moore says he's "thrilled at the prospect" of producing many more installments.

Outlander Season 1 Episode 2 airs tomorrow night at 9/8c, with a total of 16 episodes set to comprise the opening run of this series.
