The Maze Runner by James Dashner (2009) Delacorte Press

This starts with a teenager, our hero, trapped in a moving box that he finally discovers is an elevator and he is deposited in a world with other teenage boys who run the maze each day, trying to solve it so they can escape.  A girl appears a week later, not the usual month and she’s the first girl to arrive and has a message that the end is coming.  Once the hero figures-out how to escape only 40% go with him.  And in the end, we discover that everything is a lie and that was only experiment A – now on to B.
