How long does it take to travel 13 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 return to pick her up. Of course she is. Matty has heard all the impossible UFO stories for all of his seventeen years: the conspiracy theories, the wild rumors, the crazy belief in life beyond the stars. As a kid, he searched the skies with his dad and studied the constellations. But all that is behind him now. Dad’s gone and Matty’s stuck. But now there is Priya. The self-proclaimed alien girl. She must be crazy or high, right? As Matty unravels the mystery of Priya, 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.
