City of Bones. Abe Grant Adventures, #1

Dr. Abraham Grant is pulled into a dangerous new mystery when rumors surface of Tokaloma-the Dreaming City, a lost Native American metropolis said to lie buried deep within Wyoming's Wind River Range. Legends speak of a vanished civilization, impossible wealth, and a power that drove men mad. Most dismiss it as myth. But Abe is not the only one searching. Blackreach Industries, a ruthless corporate empire led by billionaire heir Elias Young, is racing to uncover the city and the vast platinum deposit believed to rest beneath it.
Backed by mercenaries and guided by Abe's longtime rival, the unscrupulous archaeologist Dr. Lewis Halberd, the expedition will destroy anything-and anyone-in its path to claim Tokaloma's secrets. Joined by Maya Yazzie, a brilliant young Native scholar with ties to the legends surrounding the city, Abe follows a trail of forgotten journals, buried ghost towns, ancient myths, and deadly clues stretching from Montana into the brutal mountain wilderness.
But the closer they come to Tokaloma, the more they realize the stories were warnings. Explorers vanish. Strange visions haunt the valleys. And something ancient still lingers beneath the mountain. Now, hunted by mercenaries and haunted by his own past, Abe must uncover the truth behind the Dreaming City before greed unleashes a catastrophe buried for centuries. Because some lost cities were never meant to be found.
