Best known for unveiling unseen worlds, James Rollins does not disappoint in his nail-biting adventure novel Amazonia.

Years after a scientific expedition into the lush wilderness of the Amazon went missing, one of its members stumbles out – a former Special Forces soldier, terrified and mere hours from death, who went in with one arm missing but now has both intact. Unable to understand this inexplicable event, the U.S. government sends Nathan Rand and a specially selected team of scientific and military personnel to follow the trail of his vanished father, the first expedition’s leader, and find out. Together, they enter a secret world of unimaginable perils toward mysteries that need to be solved at any cost. Only the nightmare awaiting them dwarfs any danger that they anticipated. Nate and his team must face an ancient, unspoken terror beyond human imagining that can forever change the world beyond the dark, deadly confines of Amazonia.
