Something big is coming big enough to destroy the entire solar system and its heading straight for Earth. Thats what Dr. Ben Rollins, head of Harvards exoplanet research team, is told by NASA after being dragged out of bed in the middle of the night. His first instinct is to call his daughter and wife, who are vacationing in Italy: something is coming, he tells them, a hundred times the mass of our sun. We cant see it, we dont know what it is, but its there. Theyre calling it Nomad, and its coming fast. In just a few months, the earth may be destroyed. The world erupts into chaos as the end approachesand Ben discovers that his wife and daughter are trapped in Italy. The key to humanitys survival may rest in the final answers he pieces together, in the midst of his frantic scramble to find his family before Nomad swallows the planet.
