This is the seventh book in the series.

1955: One of the most important computer science discoveries of the century goes missing.

Over fifty years later details concerning the whereabouts of the discovery are beginning to surface, and Sandra Swift is called upon to investigate. Accompanied by Bud Barclay, Sandy sets out on a quest to uncover a series of puzzles directing them back and forth across the country, involving them in everything from the death of James Dean to a confrontation with a giant. Sandy is at the controls of her brother's latest invention: a sophisticated computer-guided recreational which can travel on land or water, and features a detachable high-speed aircraft.

Every function of this remarkable vehicle will be put to the test as Sandy and Bud race across the country, avoiding the traps of a desperate and murderous enemy.
