Mission Earth v.2 Black Genesis

With Mission Earth, L. Ron Hubbard created an unsurpassed
masterpiece of satire, social commentary and rousing intergalactic
adventure--full of biting insights about the condition of this planet, its
people and the institutions that make it the way it is. Mission Earth, an
unheard-of 1.2-million word novel in ten volumes, is a monumental
achievement by any literary standard.
Mission Earth has an entire galaxy for its backdrop, though the main action
occurs on Earth and the planet Voltar. The Voltarian Grand Council has
become convinced that it must send a mission to prevent Earth from
destroying itself--thus allowing the Voltar Confederacy to proceed on its
long-standing invasion plan and timetable to conquer a planet they regard
as an important future way-stop on the main invasion route toward the
center of the galaxy.
The mission is assigned to a clandestine agent, Fleet Combat Engineer
Jettero Heller. Soon after arriving on Earth, he heads to New York City
where he is determined to get to the bottom of what is causing Earth to
self-destruct, unaware that his every move is being tracked and that
powerful forces on Voltar want his mission to fail.
