ler totalmente Frequency: Hard Science Fiction (English Edition)

An epidemic of suicides. A mystery buried in Jupiter's icy moon. A revelation for the ages.

The new novel from multimillion-copy international bestselling authors Douglas E. Richards and Joshua T. Calvert.

Dr. Alexandra Lennox, a brilliant neuropsychiatrist, rushes to the jungles of Colombia to investigate a terrifying surge in collective psychotic events—groups of healthy people suddenly gripped by visions, catatonia, and inexplicable mass suicides. Teaming with rugged ex-archaeologist Ethan Calloway, she braves treacherous territory to unravel the mystery as the death toll climbs. But the phenomenon is spreading fast. Can they stop it before it becomes a global catastrophe?

Meanwhile, half a billion miles away, Lieutenant Jason Crowe and three other NASA astronauts, on a clandestine mission to reach Jupiter’s ice moon Europa, discover something impossible: a perfectly geometric shaft in the ice pulsing with an artificial signal every 47.5 hours.

Two groundbreaking missions. One impossible connection. What they find will shatter everything we thought we knew about our place in the universe—and open the door to humanity’s next chapter.
