'A real space novel that predicts many of the problems that will confront the men and women who actually make the trip sometime around 2020' -- James A. Michener 'There used to be only one Mars and it belonged to Edgar Rice Burroughs ... Now Ben Bova has landed, with a new pair of eyes, and Mars is brand new again' -- Ray Bradbury 'Extraordinary ... MARS succeeds as scientific exploration, as adventure story, as a mythic tale' -- Orson Scott Caird 'a splendid book ... of his many books, MARS must be the most important' -- Arthur C. Clarke 'Gripping, realistic - don't miss it' -- Terry Brooks
