In the seventh book of this middle grade sci-fi series, teens with superpowers hijack a UFO and fly to a futuristic Earth controlled by aliens.

After discovering they are part alien, Ethan, Ashley, Jack, and Toni thought nothing worse could ever happen to them. Until an enemy attack sends them on the run—and right onto their adversary's spaceship! It seems like the perfect escape plan. When the ship lands and the hatch opens, the kids discover they are right back in their hometown of Metier, Wisconsin. Or rather, a future version of their hometown. The mall where they used to hang out has been shattered by extraterrestrial warfare. With the aliens now in charge, the teens will have to band together in order to survive. Ethan is most comfortable stepping into the solitary role of leader, but he discovers he may need his friends like he never has before. Jack and Toni are at each other throats. Ashley is running scared. They need to figure out how to fight back as a team fast, because it's going to take all their collective powers to keep them from the aliens' clutches . . .
