The journeys through space-time are increasing for Erin, Mac, Tiffany and KJ... but they are not alike. After being torn up in their time, in 1988, the four friends discovered the improbable 2016 populated by clones, giant TV and titanium creatures, before making a brief stay in a prehistoric past where a certain Qanta Braunstein taught them that she was the inventor of the journey in time. But to get the many answers to their questions, it will still take a little while... to find the trace of Tiffany, projected in 2000.
