My rating: 4 of 5 stars
So, I will say that this review would have been different if I hadn't just read another book about Charles Lindberg. So fair game- there may be spoilers on both books.
First off, I was riveted- I wanted to find out who Aces was. I kind of figured it out, but still thought it was very creative. So, here's where my review is changed. The reason the Ace of Spades would not have gone over so well without reading Candace Fleming's biography on Charles Lindberg is because I thought it was far fetched. But it's not (well, I did think the ending was over the top, but not the whole premise of the book).
Today's world, for me, is constantly opening up my eyes to several injustices in the world- our country and other countries as well. But if Charles Lindberg in the 1930's and 40's belonged to some groups that are filthy and wrong that we should gawk at, then why wouldn't that happen now? So with that being said (and probably not making sense until you read the book), I would say that the story hit on something that could happen. In addition, if you read the author's note at the end, you see where the story came from and can appreciate another viewpoint.
