While most people in America today relegate monsters to the realm of the imagination, we continue to be fascinated by the unknown just as much as people in centuries past. An authority on modern-day monsters, Linda Godfrey has interviewed eyewitnesses to strange phenomena. To be sure, Bigfoot is here, along with a plethora of werewolves, scary cats, and aliens, but so are the Oshkosh Gnome King, the Knuckle-Walking Dire Dog, the Oglala Deer Woman, and Maryland's Goat Man of Bowie. Going beyond the question of truth or fiction, Godfrey considers whether our reality is a wide spectrum with many possible answers—and none of them provable.
