A large but harmless asteroid is detected, but its course won’t even bring it close to the moon – until it suddenly changes direction and heads straight for the moon, coming close enough to extert tidal gravity on Moonbase Alpha itself before diverting again and exploding. The cause of the unusual gravity influence is discovered: a black hole close enough to divert even the moon from its path. With only three days left until the moon is swallowed, Professor Bergman devises a force field that could theoretically repel the immense gravitational stresses…but as a backup plan, Koenig has one Eagle stocked up with supplies and ready to ferry six people to safety as a lifeboat. And as the moon draws closer to the black hole, it begins to look as though the lifeboat plan offers the only chance of survival for anyone.
