Moonbase: D.U.M.B.s (Deep Underground Military Bases) - Book 4

Is there a clandestine world of tunnels and bases underground? Who is living in them? What do they want with humanity? The humans and the Greys have reached a stalemate that threatens to destroy both of their worlds, utterly. Leon becomes an ambassador, at the Grey's request, and with the help of the secret space program he travels to the Grey's planet to try and save the Earth. Leon Verdat thought he knew all about building underground tunnels. His civilian contracting business was doing well and his family thriving. Then a Man in Black forced him into the shadow world of black budgets, military underground bases, and the secret war with the Grey aliens. Leon has been left with no choice but to help a black ops military group battle invading Grey aliens from their top secret D.U.M.B.s (Deep Underground Military Bases) under the Earth, undersea--and now off-planet, as he's about to experience.
