Three years ago, a horrific accident closed ACM-1134, the energy mine on Ketarus-4. Now the mine has reopened, and Justin Barclay has joined the first new batch of miners hired to begin harvesting the energy stored below the planet’s surface. But as he settles into his new job and home, Justin quickly discovers that the mine’s polished exterior is masking a host of hidden dangers—some of them fatal. When the mine’s technology begins malfunctioning, Justin’s coworkers mysteriously disappear, get injured, and some even die. Justin knows something else is going on—and he’s the only one willing to do something to stop it. With his job and his life on the line, Justin works to uncover the mine’s darkest secrets to save himself and his fellow workers. But the company doesn’t like Justin digging where he shouldn’t be, and they’re determined to put a stop to his inquest once and for all—at any cost. As Justin begins to unearth the mine’s darkest secrets, he starts to realize that sometimes it’s better to let the past stay buried.
