In Teleport, Tim and Cal are best friends living in a small town in southeast Texas and are faced with this very problem. Seabrook, located on Galveston Bay, is usually a quiet place to live. The boys, who need extra money to purchase an X-1500 rocket system, get part-time summer jobs working in building eighteen at NASA's Johnson Space Center. 'Houdini', the ultra-secret piece of spying equipment, was locked away after the cold war with the USSR had come to an end. Join author William R. Holcomb as he describes the boys' heroic, suspenseful, and difficult journey through a complex puzzle of clues left by Mr. Winthrop.
