Senior year was supposed to be ordinary. For identical twins Juliann and Jillian Hart, "ordinary" meant synchronized schedules, matching uniforms, and a lifetime of finishing each other's sentences. But when two new students-Erik and Derek Vaughn-walk into their English class, everything shifts.The boys aren't just twins. They're mirrors.Strange reflections begin to lag behind them. Static sparks leap from skin to skin. Dreams of shattered glass and glowing water haunt their nights. And when all four dream the same dream-of a world on the other side of the mirror-the boundary between reality and reflection begins to crack.As the connection between the Harts and the Vaughns deepens, an ancient force stirs beneath the surface of their small town. The mirrors aren't just showing reflections anymore-they're trying to open.To stop what's coming, the twins will have to uncover the truth about The Veil-and decide whether their reflection is truly theirs... or something trying to take their place.
