Mines of Mars - Robert Sphar

With the expanse of Pavonis Mons behind them, Al and Lorna lead their

team into the depths of a new mountain. With the exploration of Pavonis

Mons still in full swing, they lead a small crew into Arsia Mons to start the

next phase in their adventure. There is trouble brewing outside as a giant

sandstorm threatens all of the facilities on Mars. As the extent of the disaster

becomes apparent, Al and his crew race against time and space to try to pull a

miracle out of their hats. Al and his crew must gure out the alien technology

in order to save the hundreds of thousands of inhabitants of Mars. They are

the only hope.
