Astraea

When disease nearly wipes out the human race, a telepathic teenage girl named Astraea believes her visions confirm that survivors are living in Northern Canada. She leads her doubting brother on a five thousand mile journey, through a silent America, and into the snowbound wilderness, hoping to re-build life as she knew it. As they head North, her clairvoyance leads them to encounter another couple homesteading on a remote lake in Maine.
