Signs

Close to perishing, the battered crew of Infinity One must risk their lives-and sacrifice one-to assure that human life continues on.
The crew of Infinity One must return to Earth to get a synthetic dilithium crystal from the Intercosmic Space Program's main base in Marinette, Wisconsin. Without the crystal to power their spaceship and the cloaking shield, they'll be an easy target for the Zeta aliens.
As if that wasn't enough, the sixth seal of the Book of Revelation is fulfilling its promise of stars falling from the sky and the sun becoming black as sackcloth.
It's a race against time. Can the downtrodden crew retrieve the crystal before calamity crushes them? Will they give up all hope because of the impossible odds against them? Who needs to be sacrificed to save the others? Find out in this sixth book of Seven Seals Redux.
