Mines of Mars - Robert Sphar

From the new three domed structure on the south end of Pavonis Mons,

the search begins. It soon becomes evident that they are going to need new

technology to pursue the scope of the new discovery. Al and Lorna lead their

crew deep into the mountain and together they try to unravel the mysteries

of the past ages. The discovery of the mythical garden comes soon after they

get inside, but the scope of the discovery is overwhelming. How do they

overcome the scope of the vast labyrinth that lies before them? What kind

of treasures have the previous inhabitants left for them? What mysteries lie

before them?
