Synopsis from Goodreads

Olivia Stellatella is having a rough year. Her mother left, her neglectful father -- the maestro of a failing orchestra -- has moved her and her grandmother into his dark, broken-down concert hall to save money, and her only friend is Igor, an ornery stray cat. Just when she thinks life couldn’t get any weirder, she meets four ghosts who haunt the hall. They need Olivia’s help -- if the hall is torn down, they’ll be stuck as ghosts forever, never able to move on. Olivia has to do the impossible for her shadowy new friends: Save the concert hall. But helping the dead has powerful consequences for the living . . . and soon it’s not just the concert hall that needs saving.
