A young girl befriends a time traveler on the run. Now, to save the world, she must learn to fly, track down aliens, and traverse space and time.

After thirteen-year-old Anna Armstrong loses her parents in an accident, she is sent to live on her Uncle Jack's farm. She is despondent, but on her first night there, she is awoken by strange lights originating from a nearby lake. She sets out to investigate-and the skies suddenly erupt in a thunderous explosion.

That's when Anna sees a mysterious woman floating across the lake.

She discovers Mara--the woman on the lake--is a time traveler on the run from frightening bone-white alien creatures. She also learns that time travel has consequences. Mara's time-hopping escape has broken the universe, opening wormholes throughout the valley, each leading to another world.

Now, Mara needs Anna's help--together, they must use science to track down the aliens and close the portals before anything escapes. But can they figure out how before Mara's very existence is erased forever?

Girl Out of Time is a thrilling adventure of two unlikely friends who team up to take on a world of aliens, wormholes, and time travel--to save themselves and, possibly, the entire planet.
