An exciting mystery set in a small Wisconsin town brings back the same characters from his first book, "The Other End of the Tunnel." Shawn Kelly and Steve Allison are off on another wild adventure when they are entrusted with a baffling artifact that keeps them on the treacherous edge of discovery. Vague instructions are uttered by the life-threatened victim of a mysterious accident. Those instructions manifest a secretive pact to keep priceless artifacts from falling into the wrong hands. Deception breeds cloak-and-dagger pursuit. But can thieves, kidnappers, high-tech scientists, or even the FBI compete with the cunning antics of two clever teenagers?
