From the Printz Award-winning author of Satellite comes a compelling new novel about a girl who must brave the elements to help a lost child with an otherworldly secret.

Sixteen-year-old Emily is on the run. Between her parents and the trouble she’s recently gotten into at school, she has more than enough reason to get away. But when she finds a little boy named Aidan wandering in the woods, she knows she needs to help him find his way home. But getting home is no easy matter, especially when Emily finds out that Aidan isn’t even from Earth. When their plane crashes into the side of a snowy mountain, it’s up to Emily to ensure Aidan and their pilot, Bob, make it off the mountain alive. Pursued by government forces who want to capture Aidan, the unlikely team of three trek across the freezing landscape, learning more about each other, and about life, than they ever thought possible.

I love Nick Lake’s writing. I would read anything he wrote–grocery list, email, etc.–because his writing, always, is so real and brave. He takes on subjects other writers might avoid, and he writes the hell out of them. –New York Times bestselling author Jennifer Niven on Nick Lake
