Nomad

Something massive is coming from deep space...
Big enough to destroy the entire solar system...
And it's heading for Earth.

That's what Dr. Ben Rollins, head of Harvard's 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, Jessica, who's vacationing in Italy with his wife: something is coming, he tells them, a hundred times the mass of the sun. We can't see it, don't know what it is, but it's there. NASA's calling it Nomad, and in just months, the Earth may be destroyed.
But what is it? And how did they miss detecting it until now? In a frantic race against time, Dr. Rollins must unravel Nomad's secrets. A mysterious clue surfaces in his old research papers from the end of the Cold War, more than thirty years before... 

The world erupts into chaos as the end approaches--and Ben discovers that his wife and daughter are trapped in Europe. The key to humanity's survival rests in the final answers Dr. Rollins pieces together, in the midst of his desperate scramble across continents to find his family before Nomad swallows the planet.
MORE ABOUT NOMAD
For lovers of apocalyptic fiction, Nomad is the disaster story to end them all, a cataclysm all the more plausible and terrifying as the science behind it is vetted by a team of world-class astrophysicists from CERN, SETI, the Keck Observatory and more. It even comes with its own simulation video, for those interested.

Nomad comes from the mind of award-winning, Amazon Best-Seller Matthew Mather, whose books have sold a half million copies and been translated into sixteen languages, with 20th Century Fox developing his second novel, CyberStorm, for film.
