Tunnels of Terror (Paperback)

A group of six young miners are exploring Asteroid AX245 to find the mineral ixonium. It is the most valuable substance in the galaxy and is used to power interstellar travel. The group splits into three teams to explore some tunnels in the asteroid's surface. But just before one team begins digging into the rock, they receive an urgent message. The other team reports seeing a black, gooey substance oozing out of the rock. Their report is cut off by their loud screams... and then total silence. What happened to Team Gamma? And what is the black goo that seems to have a will of its own? Can the rest of the young miners discover the truth about Asteroid AX245 before it's too late?
