When a plane crashes in the woods near Jess's home, the boy of her dreams falls out of the sky—literally. But David's not here to find a girlfriend. He's from another planet, and if Jess can't help him get back to his ship, he'll be stuck on Earth with nothing to look forward to but the pointy end of a dissection scalpel. Her father runs their house like an army barracks, and with an alien on the loose, Major Dad isn't too keen on the idea of Jess going anywhere. Ever. So how the heck is she supposed to help the sweetest, strangest, and cutest guy she's ever met? Hiding him in her room probably isn't the best idea. Especially since her Dad is in charge of the squadron searching for David. That doesn't mean she won't do it. It just means she can't get caught. As they race through the woods with Major Dad and most of the U.S. military one breath behind them, Jess and David grow closer than either of them anticipated. But David has a genocide-sized secret, and one betrayal later, they are both in handcuffs as alien warships are positioning themselves around the globe. Time is ticking down to Armageddon, and Jess must think fast if she's to save the boy she cares about without sacrificing Earth—and everyone on it.
