"The universe is not what you think it is," were the words of Aiden's grandfather, who disappeared in the Yucatan jungle twenty years ago. But when a Mars rover discovers an alien structure built by an ancient race, former Army Ranger Dr. Aiden Gunn and his graduate student Susan, find themselves summoned to Mars by a three-billion year old invitation left by his grandfather. As the world teeters on the brink of annihilation and two nations battle for possession of the ancient structure, Aiden, Susan, and the rest of the Mars team find themselves racing against the clock to understand a mystery that began before creation itself; a mystery with its roots in the great war between the angels and spanning both time and space. But within the complex, is hidden a message of hope, love and faith for themselves and all humankind.
