Outlander has not always adhered to its source material, Diana Gabaldon's Outlander series of books, so it wouldn't be surprising if Season 3 also featured a few changes. 

The upcoming season is based on Gabaldon's Voyager, which will see Jamie and Claire reuniting after being separated for close to two decades. In the book, their reunion takes place in a print shop, but the show is going in a different direction. Fans are not pleased with this, but Gabaldon seems to have given her consent.

Another change that the show is bringing concerns Claire. In the book there aren't many details about her life with first husband Frank, but the show will dive into the issues that have cropped up between Claire and Frank since her return from the Battle of Culloden.

"They've expanded that end of the story a little bit, but they've done it well, very consistently," author Diana Gabaldon, who has seen the first four episodes of the upcoming season, told TVGuide.
But the show has stuck to the books with regards to Jamie. "Most of Jamie's stuff, which is a lot of the first part, is done very straight from the book," the writer teased. "It's very recognizable, you might say."

Meanwhile, actress Caitriona Balfe, who plays Claire in the time-travel series, said there will be a lot of sex in the third instalment of the series.

"There will be some other sex going on," Balfe revealed to Vanity Fair. "I think to really let the reunion and everything that's going to happen once Jamie and Claire see each other. I think it's really special. Maybe they'll have to wait a little bit, but I don't think it's going to be as scarce as last season, shall we say?"

Outlander is expected to return to Starz in April 2017.
