True first printing in this, the fifth book in a six book adventure series. Tight, clean, flat, square, sharp book. New Old Stock: acquired in a bulk buy from a book store liquidation. It isn't brand new, but it has never been read. Interior artwork by Nicholas Jainschigg and Cortney Skinner on acid free paper. Pulp paper text block. Aaron Cofield and his friends find themselves in ancient Egypt-but an Egypt changed from the one they knew. The Sphinx now bears the head of Klaido, a savage dinosaur warrior. And the Pharoah about to be entombed within the Sphinx has decreed that all his belongings be buried with him-including the last fragment of the time-crossing roadway in this world! Aaron must race against time to retrieve the roadway and stay ahead of the savage dinosaur empire, if there is to be any hope of restoring the timestream.
