Four people in the Seattle Underground Tour vanish—without a trace. A call is put out to Special Agent Jessica Tyson. In pursuit of a murderer, she sifts through the winding tunnels under the streets and the wandering minds of homeless living above. Has the suspect created the perfect crime? He’s right under their nose, but no evidence. Jessica’s final search leads her into the unforgiving world of the homeless and the darkness of the bi-polar mind. Only through sharing a throw-away teen’s need for focus in life can Jessica capture the suspect and make her own decisions for a brighter future.
