Book Description:

When a mission from Earth explores the Stone, a strange asteroid displaced into near Earth orbit by celestial collisions on the outer edge of the solar system, they discover some strange things. First, the asteroid is hollow, encompassing four huge chambers. But even more unbelievable is that the Stone is larger inside than outside!

Soon the explorers find "The Way," a tunnel on the periphery of the fourth chamber. When the explorers try to determine the depth of the tunnel by radar-echo, it seems infinite!

A small band of humans will venture down "The Way" to discover civilizations that span time and space, as well as challenging their ideas of human society and reality itself.
