Superman: Time and Time Again — Dan Jurgens

Superman has been blasted on a roller-coaster ride through time by the Linear Man. Alone, with his memory muddled, he is propelled from the ancient past to the far-flung future and back again.  On his unprecedented journey through time, the Man of Steel encounters Nazis, wizards, demons, dinosaurs, and three different incarnations of the Legion of Super-Heroes.  Will he ever return to his own present in time to solve the mystery surrounding his journey?  Who is the the Linear Man and what is his hidden agenda?  Who are the other Linear Men?  And how does the time-lost Waverider fit in to all of this?
