The Gods of Ice

The Fifth Planet has been destroyed in the Holocaust War, and now the fate of Earth, The Third Planet, rests with Raven, the last Sword Lord of Ghedda. A gigantic fragment has broken away from the new asteroid belt formed by the destruction of the fifth planet and is on a collision course with Earth's moon. The impact will push the moon into a decaying orbit which will destroy the last life-bearing planet in the solar system. Raven's space ship can be repaired by cannibalizing parts of Zela's crashed space ship, but it will take Raven and Zela together to fly it on one last mission to deflect the asteroid. However, Raven has gone into exile with Maryam. Kananda and Zela, now King and Queen of Karakhor, set out to find them. Their twin journeys take them across Earth as it was between the last two ice ages.
