The Rithmatist by Brandon Sanderson

Joel longs to be a Rithmatist with the magical power to bring two-dimensional objects, called Chalklings, to life.  But he is 16, and Rithmatists are chosen at age 8.  Surely he has missed his chance, or has he?  When Rithmatists-in-training at the prestigious Armedius Academy begin to go missing, Joel—a scholarship student there—determines to find out what has happened to them.  Could it possibly have something to do with the Wild Chalklings of the Nebrask territory?  Could his success or failure determine the fate of the American Isles?  And, for that matter, could he become a Rithmatist, after all?
