This book starts out pretty amazing but fizzles out. Because this is a hypothetical scenario it reads a lot like fiction and allows the author to fill in the gaps as she pleases. I know this is all likely and possible but the sheer scope of devastation feels a bit numbing and by the end I was ready for the book to be over. Also, she completely ignores Africa and South America in book which I hated because in a nuclear WW3 scenario those people and places would be impacted as well.
