WELCOME TO MAINFRAME... They say that the past is behind us but it really depends on your point of view. The past is not necessarily behind you if you have the codes to the archives of history in the mainframe of the universal matrix. And somebody does.... Tamar and Denny have to embark on a perilous and sometimes hilarious journey through time to apprehend the now insane Askphrit before he alters history forever and wipes them both from the face of the earth. It is a journey that will take them to hell and back and much further. Can they, even with the help of Jack Stiles, Hecate, Cindy and Eugene, stop Askphrit before it is too late?
