Publisher Blurb: The Surface World is Wasted With each rising moon comes the surface-blasting meteors of the lunar rain, destroying everything living below. All the major cities of DragonMech are reduced to rubble -- except for one. The free city of Edge, carved into the solid rock of a 2,000-foot tall cliff, still stands under the protective wall of its cliff face. One City Still Stands Built into a natural cavern above a towering waterfall, Edge is the world's busiest trade port. An ancient river flowing from the heart of the underdeep divides the cavern in two. Each bank is a city unto itself -- as is the nearby cliff-dweller settlement. No government has ever united these disparate populations. Will the rising mechdoms claim this merchant jewel? Or will Edge remain a rough-and-tumble frontier town like it's always been?
