Thunder Under Stone

Karswick's abandoned mines were supposed to be safe. Then a seven-minute storm strikes the mountain town while forty-three tourists and staff are underground. When the darkness lifts, seventeen people are missing—and six strangers have appeared inside a chamber sealed for decades. None of them knows how they got there. Atmospheric physicist Dr. Sabine Ketter joins search-and-rescue specialist Tomas Grell, geophysicist Imogen Strake, signal analyst Nolan Saye and investigative journalist Adrian Kell in a desperate search beneath Karswick. But the deeper they descend, the less the mine obeys ordinary space. Passages connect to the wrong levels. Voices travel through dead equipment. Objects from distant storm sites appear far below ground. And someone is sabotaging the rescue to keep the most important evidence buried. As hostile operatives close in and the workings begin to flood, Sabine's team must discover what happens during the storm's most dangerous minutes before the mountain becomes a trap with no reliable way out. Because Karswick is not merely another storm site. It may prove that the impossible locations touched by the seven-minute phenomenon are physically connected.
