In this pulse-pounding sci-fi mystery, one physicist will discover that everything humans thought they knew about space and time was wrong.

Former fighter pilot and physicist Dr. Melody Adams was once a rising star in the NASA astronaut program. Now, she’s grounded in Hawaii, observing the night skies through the Gemini North telescope. But what she’s just seen could change everything.

When Melody notices what looks like a comet near Pluto—a scientific impossibility that far out in the solar system—she’s convinced she’s made a major breakthrough, even as other scientists dismiss it and she becomes a laughingstock. Whatever it is, it’s moving fast . . . and headed toward Earth.

Two years later, the object is spotted again, closer than ever before, and it seems to be slowing down. Suddenly thrust into the spotlight, Melody becomes part of a team tasked with investigating what is now suspected to be an extraterrestrial vessel. She’ll get a second chance to head into outer space, and Earth may get its first chance to establish contact with an alien intelligence—assuming it hasn’t come to destroy humanity . . .
