Daphne, her husband and 3 kids live in Miami.  He is a surgeon and they live in a well-off community. This story follows them as Miami is hit by a category 6 hurricane.  This is set in present day as climate change is starting to effect the US - fires, stronger tornados, stronger hurricanes.  Miami is wiped out and all the refugees are relocated by FEMA to megashelters.  Houston is also wiped out by the same hurricane.  I liked that this story doesn't focus on a global diaster but rather a more realistic US diaster and how the government deals with it.  How prepared are we?  Well written and I cared about the characters.  Recommend.
