So I read through this and loved it. It wasn't until I finished the book that I read the author bio and learned that she had written another book that I loved called "Draw the Dark". Ilsa Bick just has a writing style that I enjoy. It's super suspenseful, but the characters are always believable and the story lines run along the lines of supernatural and sci-fi that steps into "this could be believable". Also, I will read a zombie book if it's good and I'm in the mood, and this book borders on zombie fiction, but not quite. I like how the author makes up a somewhat believable scientific exlpanation as to why only people over 12 and under 55 are affected by the EMPs. Also, there is blood, guts and gore! I don't mind much, but some readers might. The characters were great, and even though the author started leaning towards the dreaded teen-book-love-triangle towards the back of the book, it was no where near as annoying as it could have been. Can't wait for the sequel, because the ending will really leave you hanging!
