Ender's Game

“This is not a game.”

The alien invasion is coming, but no one at the academy will say when, only that Earth has already chosen who will stand against it. Colonel Hyrum Graff (Harrison Ford) pulls Ender Wiggin (Asa Butterfield), a gifted child, into a military school in space, where Gavin Hood sets the students against each other in training games. Ender keeps winning, and each win places more weight on a child who never asked to carry it.
