Really enjoyed the first book. Good foundation building, character intro and then the EMP. All well done; a real page-turner.
The rest of the books did a good job laying out some possible scenarios for post-EMP life, while weaving in survivalist tips.
Because books 2-4 are scenario and character specific, they just can’t be as intriguing as the first book.
Overall – 4 stars. Book 1 = 5 stars.
