Distant Cousin

A lonely astronaut stumbles upon a disaster in the making: the Earth will be turned into a crater-pocked ruin and millions of people will be killed, unless she can convince someone to take preventive action. But she has a huge problem. After all, who would believe an ordinary young woman who said such a thing, especially if there is no record she is an astronaut.and especially not if she also claims to have come from a different solar system? Only the U. S. government does, and hunts her with all the forces it can muster. Terrified and with few resources, she tries desperately to disprove people's low opinion of what a young woman is capable of. And what about her earthly boy friend? Would he believe her, or sell her out?
