I don't go in much for horror and if I do, it's more likely to be vampires than zombies...but THIS, this is different. This is wonderful. A zombie book that had me crying like a baby. Twice. 
 OK, so the constant describing of the bloodtests and the sunglasses thing did get a little bit tedious at times, but I think it was necessary really, to help get across the total difference in a post-Rising world, and to understand the paranoia and fear of that world. 
 And Grant created characters that you could relate to and care about (hence the crying lol) but I haven't tagged spoilers so I'll leave you guessing about the tears ;-) 
 Just read the damn book!
