Against the Darkness — A.M. Griffin

Seventeen year old Sinta Allen has one objective, to get from Tallahassee, Florida to her mother in Ann Arbor, Michigan. Seems simple enough right? Wrong. Hostile aliens have invaded Earth -- and it doesn't take a rocket scientist to know that we're losing the fight. While the aliens bring devastation and destruction and take people away to God knows where in their spaceships, Sinta, along with some of her classmates must rely on their survival instincts, a little luck and each other if they want to survive the venture across the country. The last thing she needs is for Wade, her school friend and Jason, her rescuer, to distract her along the way.
