People in Glass Houses

＂His name is Joshua Knight. Once a respected explorer, the press now calls him the Tarnished Knight. He took the fall for a disaster that occurred in the sector known as Glass House. Now a recluse, Josh spends his days trying to discover the secrets in the looking glasses that cover the walls. Crystal artist Molly Griffin heads for the mansion to find Josh. He is the key to finding her sister, Leona. Josh reluctantly allows her to stay one night but there are two rules: she must not go into the basement, and she must not uncover the mirrors that have been draped. But her only hope for finding her sister is to break the rules.＂--Publisher description.
