So, so, so good. Entirely unlike anything else -- sort of like if the kids in an E. Nesbit book were transplanted to the 21st century and faced with the third world war. Loved Daisy's sarcastic narration and authentic teen voice. Very unusual and quite captivating, not at all what I expected. Hard to say what genre this even is -- not sci-fi, but not quite contemporary, and not really fantasy either. I guess more of a survival story than anything else.
