Decent, scary, "the poop's hit the fan, and we've got to scavenge supplies and then hole up at home and try to survive" novel in the vein of Richard Matheson's I Am Legend, Chris Adrian's The Children's Hospital, Emily St. John Mandel's Station Eleven, Daphne du Maurier's "The Birds," and so many others, although not as good as the last two in that list. 
 It's a little light on character development (it seemed like there were about three personalities stretched across about eight characters), and there were some plot holes (I do not understand how their food lasted as long as it did or how a hugely pregnant woman could lean across anyone without her belly getting in the way, and the thing with the dogs was just annoying), but it moves along quickly and is fun to read as long as one doesn't expect too much from it.
