I expected a book about women in the war, and I got a romance drama with a war setting. Why is it called the women, plural, when the friends are side characters to one woman who mostly focuses on the men around her?

It wasn't a bad book. There was a lot of good things about it, and I respect the difficulty of writing such a complex subject. But it felt dark in a drama way, not a real way. The insights into wartime nursing conditions, I have seen other reviewers say, are somewhat accurate. But that got repetitive fast and didn't elaborate.

I didn't like the main character or any of her romantic interests, and that was all there was to the book (besides parental drama, some PTSD and addiction that was wrapped up in heartbreak). It seemed to touch on a lot of things that are known struggles for veterans, but not actually go in depth. And focused wayy too hard on the ~but wait he didn't die~ tropes that are so predictable it hurts (twice!). The choices she makes in men are unbelievably stupid. Of course I don't want to blame her for the men's horrible character but she really doesn't help herself out in that area. I wish there was less awful romance and more of the great friendships. I loved Barb and Ethel. 
Other things that I found weird- Why is there not even one Vietnamese character? How does she become such an amazing surgical nurse that she is first assisting with no scrub experience? (I get you gotta learn quick and it's all hands on deck in these situations, but that doesn't provide good learning conditions?) 
A lot of this book felt clean, simplified, and romanticized. Some of it also felt negatively exaggerated (the response coming home) I heard such good things about the author and the writing quality but she really modernized the dialogue in a way that felt disconnected, and didn't have any developed supporting characters. I'm left disappointed.
