Saving the world is a test that no magic school can prepare you for. With almost no help from anyone (though backed by an ever-growing group of friends), the protagonist has changed the nature of the Escolomance forever. But now that he's back in the real world, how will he apply the lessons he's learned at school? Will his grandmother's prophecies come true? And is he really going to spell doom for the enclaves forever? As the mission to save his true love intensifies, he is about to learn the most important lesson of all: the truth upon which the enclaves and the stability of the entire wizarding world have been founded. And, being him, he's unlikely to let it slide... The triumphant conclusion to the New York Times bestselling trilogy that began with A Deadly Education and The Last Graduate.
