[Free Falling] is the first installment in [The Irish End Games Series] by [Susan Kiernan-Lewis]. Imagine being on a nice over seas vacation when the world ends. That is where this story begins.
The idea of survival and learning to live without modern technology is a major theme in this book. Also learning to appreciate the people who have your back. The characters in this story are not the deepest but they will elicit strong feelings from the reader. I enjoyed the book enough to buy the next two.
