I'm looking for a post-apocalyptic story about some sort of energy field or bubble that appears over the United States one day and turns people into some kind of soup or goo. It killed pretty much everyone inside.
One of the main characters was an army officer; I think he was stationed at…Guantanamo Bay? The edge of the field was nearby on the island of Cuba.
The rest of the story was about trying to figure out the cause of the disaster. One day a few years later, the bubble just disappears as quickly as it came and people start rushing back in to secure all the left-behind belongings. That part might have been in the second or third book though.
It was a paper book I saw about 5-6 years ago. I know it’s pretty slim but has anyone ever heard of this book?
