Weird things began to happen, Tina noticed, right after the explosion in the subway. Stuff was disappearing-ordinary things like the closet doorknob and Tina's best sneakers, highly improbable ones like the kitchen linoleum, and most amazing of all, the great bronze statue of King Jagiello in Central Park.

The three punky guys who kept turning up, with their chains and wrist straps and jackets lettered "Prince of Darkness" across the back, were obviously part of the terror. But it wasn't until Tina met the old street fiddler Paavo that she understood the menace that threatened the city and her own role in the terrifying struggle that lay ahead as an evil power from another dimension challenged her world.

Here is a brilliant and compelling fantasy, which builds irresistibly from its everyday beginnings at a subway station on Manhattan's West Side to an epic battle in Central Park.

Music and magic conspire together as Tina, her new friend Joel, and the ancient wizard Paavo join forces to defeat an awesome enemy.
