Pillar of Darkness — Dave Duncan

A mysterious adventure awaits nine strangers who venture inside a dangerous region that defies science, in this novel by an award-winning author.

Thirty years ago, a terrifying anomaly known as Sungoback appeared over North Africa. Two hundred miles wide, the mysterious zone manifests as a pillar of darkness during the day and as a pillar of light at night. There is no telling what secrets it holds inside, as it defies science and destroys technology. Entering Sungoback is considered tantamount to suicide since most who do so are never seen again. 

Now, nine strangers are headed to Sungoback. Each has their own motive for risking everything to enter. They should hope they don't all share the same fate inside . . .
