Third book in the science fiction series “Red Desert”.

The joy of finding the small community living in Ophir is soon shattered by the news coming from Houston about the loss of contact with Station Alpha. In fact for more than a day now, no life signs have been detected inside the habitat.
So, together with Jack, Anna sets out for Lunae Planum again. She's assailed by dread about Robert's and Hassan's fate, and also by doubts concerning their involvement in the death of both the Isis mission commander, and most of all, his wife.
However, having to face Michelle's murderer is only the first of her problems.
Torn between the desire to return to Earth and the ambition of getting the credit for her scientific discoveries, Anna will see her feeble certainties waver several times, until the revelation of a more devious danger concealed by the Red Planet: an invisible enemy, whose mysterious intent menaces her existence and the one of the only person who is still at her side.
