Rowan Farenhave lives in a city, the Acropolis. Her city is filled with equal magic and technology, a formidable duo that protects and conceals the cities from outer horrors. But there's a war going on. A major war that only anyone from age eighteen to twenty can be part of. And sixteen-year-old Rowan must take the test, the one that proves whether she can be part of this war, or die in the process.
