Reed Shelton organized this survival weekend. Hired the best guide in the region. Meticulously trained, studied, and packed while encouraging his wife, Beck, to do the same. But little did they know that surviving the elements would become the least of their worries. During their first night of camping, an unearthly wail pierces the calm of the forest. Then someone—no, something—emerges from the dense woods and begins pursuing them. Everything that follows is a blur to Reed—except for the unforgettable image of a huge creature carrying his wife into the darkness. Dependant on the efforts of a small town and a band of friends, Reed knows they have little time to find Beck. Even more important, he soon realizes that they aren't the only ones doing the hunting. Something much faster, more relentless—and definitely not human—has begun to hunt them.

These words, spoken to Brian Robeson, will change his life. Two years earlier, Brian was stranded alone in the wilderness for fifty-four days with nothing but a small hatchet. Yet he survived. Now the government wants him to do it again—to go back into the wilderness so that astronauts and the military can learn the survival techniques that kept Brian alive.

This time he won't be alone: Derek Holtzer, a government psychologist, will accompany him to observe and take notes. But during a freak storm, Derek is hit by lightning and falls into a coma. Their radio transmitter is dead. Brian is afraid that Derek will die of dehydration unless he can get him to a doctor. His only hope is to build a raft and try to transport Derek a hundred miles down the river to a trading post if the map he has is accurate.

Spinoza wrote in the rationalist style of a geometric proof to develop his idea that God is a permanent, indwelling cause of all things. He sees God as a single, unified, all-inclusive causal system that is virtually synonymous with nature. Spinoza believed that the Biblical account of creation is demonstrably false; that there is no such thing as a free will, either for God or man; all things are necessary and inevitable; and all objects, including humans are part of God's active self-expression. Spinoza saw the presence of God in the constant and orderly working of nature.

Spinoza's sophisticated moral psychology sees evil in the "unruly passions," and says they can be overcome by stronger, positive passions. Our minds can participate in the eternity of God by focusing on natural laws and the way all things follow from God or nature.
