Starz is renewing "Outlander," the historical romance adapted from Diana Gabaldon's international bestselling books of the same name. Season two of the series will be at least 13 episodes and will be based on the second of eight books, "Dragonfly in Amber."

The "Outlander" series is part romance, science fiction, history, and adventure all mixed in one. It centers on Claire Randall (Caitriona Balfe), a married combat nurse from 1945 who is inexplicably sent back in time to 1743, where she is forced to marry a Scottish warrior named Jamie Fraser. The books follow Claire's love for two very different men in two very different time periods.

The first season, filmed on location in Scotland, set multiplatform viewing records, surpassing 5 million views in the first week alone, with equal male and female viewership.

Starz Chief Executive Officer, Chris Albrecht commented: "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."

Creator Ronald D. Moore added, "This project has been a labor of love from the very beginning and it's incredibly gratifying to see it succeed with viewers and critics alike."

Gabaldon's eight-book series has sold more than 20 million copies and has graced the New York Times Best Sellers list six times.
