I absolutely LOVED this book. It was very long, but every bit of it had me on the edge of my seat. The love story between Claire and Jamie is epic. This book was great because it included a little bit of the fantasy, scifi that I love - in the form of time travel. But this book cannot be categorized as scifi as most of it is historical fiction, set both in the 1940's and the 1740's Great Britain, particularly Scotland. For anyone interested in Scottish history, you will love this one. It is worth the length of the book. 
 I think my most favorite scene from this book is when Jamie and Claire go back to the hendge that she originally came through and her subsequent return to Jamie the next morning. Beautiful and so memorable!
