When Kyle Chase accepted his Aunt Cindy’s invitation to spend his summer vacation with her, he thought they would be exploring old caves, looking for arrow heads, and honing his skills as a young Archeologist. He never dreamed the fate of the world would rest on his small shoulders. Kyle, his aunt and a small group of travelers have been imprisoned by a mad-man.
