This is my least favorite of the entire series of Outlander books and yet I give it a 3. It tells you something about the series. Diana Gabaldon is an excellent writer who deserves the recognition that she gets and more. 
 Now, the reason for the 3 is that the beginning of this book and some of the fighting and war scenes in this book are long and drawn out. They are hard to get through. And yet just when you feel like Diana has left the story to tell you about the scenery, something grabs your attention and makes you gasp or make some other involuntary noise. 
 This book, so like the others, is filled with intrigue and obstacles that make Jamie, Claire, Brianna and Roger's lives more interesting than they have a right to be. 
 I feel like this is more Roger's book as one of the biggest things in the series happens to him and we get to see the results and change go through him. 
 Diana has a great talent for writing for these characters and is wonderful at her portrayal of small children. Jemmy is great as is Germaine. 
 I do feel at times that Diana uses more words than are strictly necessary but at the same time it is why you feel like part of this world. 
 I would highly recommend this series of book and I would say stick it out when some parts become a little too descriptive because the end result is always worth it.
