This is a page turner. I thoroughly enjoyed this book. I did wonder about the timing of it. 2023 is far too soon for all the events to have happened by then. Very high risk research strategy to get a cure/vaccine for the decease. I would have imagined hearing for the lab directors on Capitol Hill demanding to know why the world wide research effort hadn't produced any results before the events that that happened in the novel took place. My feeling is that the political heat on the directors of the CHGA would be enormous.
