A beautiful and affecting book
Format: Hardcover
A beautiful and affecting book. The civil war is, at least to me, deeply familiar, but this book focuses on the personal, and conveys with a painful immediacy the ways that the horror of this conflict infiltrated and transformed the day-to-day existence of our not-so-distant ancestors. I was struck as I have never been before by the degree to which the appalling, unprecedented violence of the conflict was "just around the corner" for familiar and modern-seeming Americans.

... our traditional textbook and primary sources) and my students LOVE it. Although it's not perfect
Format: Hardcover
I have started using this in my US history survey class (along with our traditional textbook and primary sources) and my students LOVE it. Although it's not perfect, it's a great complement to other sources and offers a terrific way to talk about alternate ways to interpret history. In addition, my 11 and 14 year old sons have also read it and enjoyed it, so it's accessible for a broad range of ages. And, as my students note in their final papers, it's fun to read, and how often do gen ed students say that at the end of the semester?

Carry on with the great writing Rachel Lacey while I look for my next bodyguard book
Format: Kindle
I'm on a bodyguard reading kick right now, only wlw of course. I read this one for the first time about a year ago and somehow, I didn't leave a review. ( I'm good at hopping from one book to another and forgetting to write one. oopsy) I loved the bodyguard part but as stories go I always hate someone's parent dying. ( too much like real life) I know it's necessary to show why Natalie is so effed up. Rachel wrote a great ending to this story and that is always a plus in my eyes.

I really enjoyed the storyline and the emotional growth of the characters in this book. I’d been putting it off for a while but I’m glad I finally picked it up and took a chance on it because it was such a cute story.
