Leon Verdat thought he knew all there was to know about building underground tunnels and structures. His civilian contracting business was doing very well and his family was thriving. Then, he got a visit from a mysterious Man in Black and all that changed.

He was introduced to the world of black budgets and secret military underground bases; the work of the "shadow government" and the ultra-rich. Now, his life will never be the same again, if he survives...

There are a lot more things than he bargained for deep underground, and some of them have been here for a very long time.

The inspiration behind this book series?

Many late nights listening to Coast to Coast AM, since the early days of Art Bell, where he'd have many guests on that talked about aliens and underground secret bases (mostly in the southwest USA desert, like Area 51, but also bases all over the world), like Whitley Strieber, Richard Dolan, Roger Lear, Richard Sauder, and more.

Guests spoke about real life bases and also told some fictional stories. Some spoke about both.

These books take a sampling of the facts that have been made public about D.U.M.B.s and adds some imaginative speculation to create a brand new, wild fictional ride!
