The Silver Citadel — Anthony Horowitz

CAN TWO BROTHERS' LOVE DEFEAT THE “OLD ONES”?

It is as if they share one heart in two bodies -- the force that binds Nicholas and his twin brother Jeremy is so strong. But Nicholas is the weaker of the two, and when Jeremy senses the evil coming. Nicholas feels powerless to stop it.

Then Jeremy is taken by three masked men, and it is the union the brothers share that gives Nicholas the strength to begin his search. A stranger in New York, he is guided only by the inner voice that tells him Jeremy is alive somewhere in the city. And that the nightmare has something to do with a place called THE SILVER CITADEL
