Exodus From Orion

Bob's having a bad day. Dumped by his girlfriend, fired from his job, evicted from his apartment, and beaten by an old lady in a bar, things couldn't possibly get worse. But when he travels high into the Sierra Mountains to get away from his troubles, he hears a voice coming from a star hundreds of light years away, what happens next could determine the future of life on Earth, and the fate of humanity itself.
