Burn Out by Kristi Helvig

A futuristic blend of Beth Revis's Across the Universe and Lenore Appelhans's Level 2, Burn Out will satisfy the growing desire for science fiction with a thrilling story of survival, intrigue, and adventure.

Most people want to save the world; seventeen-year-old Tora Reynolds just wants to get the hell off of it. One of the last survivors in Earth's final years, Tora yearns to escape the wasteland her planet has become after the sun turns "red giant," but discovers her fellow survivors are even deadlier than the hostile environment.
