for Escape the Vortex by Jeanne DuPrau
Earth is in danger! The only thing that can save our planet are six essential elements that can fuse into a new source of clean energy. But the elements are scattered throughout the galaxy. And it's up to the Voyagers--a team of four remarkable kids and an alien--to gather them all and return to Earth.
The Voyagers' fifth stop is Planet Tundra and it may look like a giant marshmallow, but this is no winter wonderland--it's a winter nightmare! This frozen landscape is the deadliest the Voyagers have encountered yet. Then, when the Omega team finds themselves in trouble, only Team Alpha can save them. But if the tables were turned, would the Omegas do the same?
