From the introduction:
There is more to the world than most people know. The paranormal and the supernatural, believed to be mere fantasy stories and campfire tales, are very real, and more often than not, very dangerous. Ravenous carnivorous insects from prehistoric times lie dormant inside the trunks of ancient trees. A tribe of feral humans lives in the wilderness of New Jersey, killing anyone who gets too close to their young, and spawning the urban legend of the Jersey Devil. A species of parasitic worms, carried to Earth hundreds of thousands of years ago by a falling meteor, lives frozen underneath the Arctic ice sheets. Psychics and mediums are able to foretell the future and see through the veil of reality. The souls of the dead can communicate and interact with the living, and an extraterrestrial civilization has been manipulating human civilization for their own sinister ends since life first appeared on Earth.
