The Sun is Not Ours by Loraine Hambly

The Sun was created six thousand years ago, two thousand years later it deliberately set Mars alight and it will do the same to the Earth in 2025 unless humanity steps up now to prevent it. Spirit confirmed to me the burning of the Earth, saying, "2025 is the year of evil", "The Earth will burn for four years", "The time of fire should be taken seriously from start to finish", and "The world will be turned to ruins," that "The threat is very serious" and that "Terrible things are going to happen".
