Extreme Disasters: Planetbreaker

By Robert Castleberry

When a record-breaking magnitude 12 earthquake tears Redridge Valley apart, thirteen-year-old Levi is separated from his family and pulled into a hidden world buried deep beneath the Earth. There he uncovers an ancient machine unlike anything ever discovered, hears mysterious whispers that seem to come from the planet itself, and learns of a secret known only as Operation Planetbreaker.

As Levi races to escape collapsing tunnels and survive the deadliest natural disaster in history, he experiences terrifying visions of even greater catastrophes still to come. But when a powerful government director warns him that he is "one of them," Levi realizes the earthquake was no accident-and that he may be connected to an ancient mystery stretching back to the beginning of time.

Back on the surface, Levi struggles to rebuild his life while the world searches for answers. Refusing to stay silent, he begins a search for others who may share his impossible connection to the Earth, unaware that his journey is only just beginning.

Filled with breathtaking action, unforgettable friendships, humor, suspense, and mystery, Planetbreaker is the thrilling first installment in the Extreme Disasters series-where one earthquake changes everything, and the fate of the world may rest in the hands of ten ordinary kids.
