"DEEP SPACE.  DEEP TROUBLE.

   The man they call Diego was a tough hombre looking to escape a jam.  But the time machine he found took him out of the frying pan and into the future.  Now he's gone from the wide-open spaces to outer space---in the 26th century, as the starship Angus goes to war....

    Before you can say "Beam me up, Scotty," Diego's risking his neck against a female terrorist known as the Space Avenger----and the weirdest life-forms he's ever seen outside a bottle of bad whiskey.  But then again, they've never seen anything like the man they call Diego!"
