Dark Nights by Christopher A. Gray

Astrophysicist Doug Lockwood has made the discovery of a lifetime: another planet has appeared in our solar system, in orbit opposite that of Earth. Its sudden appearance is unexplained, but the danger presented by the alternate Earth is real.

“Innovative and well-paced… part scientific exploration, part action, part political intrigue, the combined result is a page-turner.”
