First of all you must like EMP/Post-Apocalyptic book as some of the book could be realistic while a couple not. The main characters of the book are Maddie (a teenager and runner) and Emma (10 yr. old who just witnessed her parents’ murder) who are escaping the dangerous airport in Chicago to get to her Uncle Ryan in Illinois. Both running the distance in short period of time with little food and water hard to believe Emma could do this and going thru what horrendous events that took place as well as the dog Cooper then her brother Jake arrive shortly after. But have to admit I enjoyed the book and await next book. I was given this free review copy audiobook at my request and have voluntarily left this review. Thank You!
