There is a series by Bethany Claire, the collection referred to as Morna’s Legacy series. It has similar themes.
I was thinking perhaps Bree got some antibiotics and advice on how to possibly manufacture more from Uncle Joe, remembering things like Jamie’s snakebite and being fearful of her children perhaps needing modern medicine in the future. I also think she will have brought a few small tools with her (like her knife), maybe some seeds that were unavailable in North Carolina, and Jamie’s wooden snake.
I’m curious how the story will play out seeing as Murtagh is a sort of stand in for Duncan. Many story arcs (as in the “situation” regarding the marriage of Duncan and Jocasta, and the subsequent attempts at stopping the union) will have to be tweaked. I’m quite fond of Murtagh’s character in the show, just wondering how different the situations will be.
