Basically, this is a huge reference for all things related to Outlander - covering books 1 - 4, and also including a bit of information about the later books. The synopses of the books are really great as they help to refresh one's memory about what happened in each book. My favorite part was definitely the section written for ladies, lol - specifically about not actually sitting on the toilet seat. It was truly an outlandish part, but I found it hilarious and I completely agree! I also loved learning more about Ms. Gabaldon herself and seeing her interactions with her internet friends. I skimmed over some bits like the bibliography, the Gaelic translation and pronunciation guide. Since I listened to the audio and didn't read the books, I'm really grateful to Davina Porter as I don't have to worry about the pronunciation. The best parts for me were the sections when she talked about her writing process. It gave great insights. I also really like her snarky attitude and the fact that she freely admits she doesn't play well with others. Diana, you're speaking my language! It's a great reference to have or peruse (even though it's not cheap, even in the ebook version) for those who love the series and want to know everything.
