Fasten your seatbelts.

Mission Earth is approaching climax . . .

And it will rock your world!

Who will control Voltar?

What is Earth's ultimate fate?

And what is the big mystery?

The wait is over. Powerful forces are on the move. Entire planets hang in the balance. The moment of truth is finally at hand—and it's a real blast! In the middle of it all stands Royal Officer of the Fleet, Jettero Heller, a man determined to save both Voltar and Earth from extinction.

Together with an outlaw emperor and an army one hundred thousand strong, Heller lays siege to Palace City, which has fallen into the depraved and diabolical hands of Lombar Hisst. But the success of Heller's great adventure is far from a sure thing. For in order to achieve victory, he will not only have to break the laws of Voltar—but defy the laws of physics.

Here is your ticket to travel beyond the boundaries of space and time. Experience the unfolding mysteries, the violent pleasures and the biting, inescapable truths you can only find in the final reckoning of THE DOOMED PLANET.
