Rover Mars

The crew of the Victoria Rover are back. This time it is not the International Space Station that is in jeopardy, it may be the human race.
An international manned mission is approaching Mars when a US Navy ballistic missile submarine mysteriously appears on a plain near the planet’s equator. Critics of the American administration both foreign and domestic raise the specter of global warfare at this supposed breach of international agreements on the proliferation of weapons in space, especially nuclear weapons. With the world on the brink of catastrophe and the crew of the submarine facing death, Peter and Sandy along with their companions, Mike and Christine brave seemingly insurmountable odds on an attempt to rescue the crew and put a stop to the madness.
The second book of the Rover Trilogy, with Rover to the Stars coming in the Fall of 2020.
