Quarantine Book One by Lex Thomas

Back to dystopia!  At the urging of a student, I finally read the first book in the Quarantine series, The Loners.  As I read it I couldn't help but think of the first time I read Lord of the Flies.  There are lots of connections with the classic.
Imagine it is the first day of school.  As the day begins you are visiting with a favorite teacher.  Suddenly, a horrific explosion rocks the building.  Chaos ensues.  This is exactly how David's first day of school starts.
The smell of smoke and panic fills the air.  In front of David his teacher starts to convulse, dying a horrible death.  Every adult in the building dies the same way.  As students run to escape, the military shoots them down.  What is happening?
Students have become infected with a virus.  When transmitted to adults it causes a horrible death.  The military has locked down the entire building.  As days draw into weeks and months, students align themselves with gangs.  The military drops food and supplies, but students battle for whatever they can get.  David and his younger brother Will have made their home in the elevator shaft.  Will this nightmare ever end?  Read the book to find out!
