Something is devouring Earth. . .

A suburban house in Oklahoma vanishes into a roaring abyss. A supertanker at sea suffers a fiery destruction. A blast in China drills a gigantic cavern into a mountainside. A severed arm plummets from the sky in Missouri.

Could these catastrophes possibly be related? Intrepid geologist Dacey Livingstone is nearly killed by her first attempt to plumb the mystery—a perilous descent into a house-swallowing sinkhole. Still determined, she joins with eccentric physicist Gerald Meier in a quest that takes them from the ocean’s depths to interstellar space.

What are these exotic “wormholes” that threaten Earth? Can their secrets be discovered, their power even harnessed? Or will they spawn a celestial monster that will annihilate the planet?

Veteran science writer Dennis Meredith has crafted this cosmic adventure drawing on his decades of experience working at leading research universities such as Caltech, MIT, Cornell and Duke.
