Yes it a story of a group of people who are in all the books some die and then are alive in the next book sounds good but as you listen to the audibles you start to see a pattern first nuclear, then flooding and now a virus all the same people but different lives and death. This is a made made virus that goes wrong and start killing everyone the main characters and people around them. You see a government that goes crazy and start killing and burning the sick or dieing all over LA and other places in the US.
The one draw back with this audible the listener is left hanging wanting to know what happen to the core group of the main characters we know 3 to 4 have died but the others are either well or maybe dieing but then the audible . As you listen you find it was plan to see how people would survive in different events but doing it in a simulations they are alive thru all events and previous experiences are dejove or a nightmare that comes from headaches and other systems.
I hope the next audible will pick up were this one stopped and start really pulling all the experiences into a outcome that settles the lives of the core group who have both lived, experienced and died from from these scientific experiments
