Pit Planet

Trapped in the underground tunnels of Colliery, James Benton struggles to find his way back to the surface and the life he knew before. A headlong trip over, under, and through worlds of greed, sex, politics, intrigue, and adventure, of miners and mindpickers, cavesnakes and triple-crossers. An absorbing mix of hard science and action sf, with the unmistakable Dvorkin touch. - Connie Willis
