A heart-wrenching romance full of twists that are sure to bring tears to readers' eyes, from Cat Jordan, author of The Leaving Season.

How long does it take to travel twenty light years to Earth?

How long does it take to fall in love?

To the universe, eight days is a mere blip, but to Matty Jones, it may be just enough time to change his life.

On the hot summer day Matty's dad leaves for good, a strange girl suddenly appears in the empty field next to the Jones farm--the very field in rural Pennsylvania where a spaceship supposedly landed fifty years ago. She is uniquely beautiful, sweet, and smart, and she tells Matty she's waiting for her spaceship to pick her up and return her to her home planet. Of course she is.

Matty has heard a million impossible UFO stories for each of his seventeen years: the conspiracy theories, the wild rumors, the crazy belief in life beyond the stars. When he was a kid, he and his dad searched the skies and studied the constellations. But all of that is behind him. Dad's gone--but now there's Priya. She must be crazy...right?

As Matty unravels the mystery of the girl in the field, he realizes there is far more to her than he first imagined. And if he can learn to believe in what he can't see: the universe, aliens...love...then maybe the impossible is possible, after all.
