Jay Cantrell will find his daughter...or die trying.

He had the perfect life as a small-town librarian: married just over a year to a beautiful airline pilot and with an daughter in college studying to be an astrophysicist. He's ready to celebrate his first anniversary as he adjusts to the empty nest.

But the sun had other plans.

Awakened before dawn by northern lights—in Illinois— that covered the entire sky, Jay's entire world changes in the blink of an eye. Flying a planeload of passengers to Hawaii, Kate experiences the coronal mass ejection in a whole other light and must fight to stay alive every step of the way. Leah, Jay's daughter, is left stranded at college and witnesses the collapse of society through the eyes of a student far from home.

Jay sets out to rescue his daughter and must make a harrowing journey through a post-apocalyptic wasteland as the rest of the country comes to grips with just how serious things have become.
