How The Outlander Book Series Lines Up With Each Season Of The Show (& What Changes)

The Outlander book series is an epic nine-novel story that serves as the source material for the popular Starz show of the same name and, for the most part, the seasons faithfully adapt the books in order. Author Diana Gabaldon wrote the first novel in the series, Outlander, in 1991. The following eight books were released over the next 20 years, with the longest pause between publishing being between book eight, Written in My Own Heart's Blood (2014), and book nine, Go Tell the Bees That I Am Gone (2021). The Outlander series also includes spinoff novellas, graphic novels, and audiobooks.
