Diva Delores and the opera house mouse

Tra la la la! Can an opera house mouse and a disrespectful diva make beautiful music together?

Maybe . . . if she learns some manners! Fernando loves Mozart, Puccini, and Strauss, and lending a paw at the old opera house.

Unfortunately, diva Delores wants no help from a mouse.

She craves glamour and spotlights and praise-and she's getting her chance to take center stage.

But it's all going wrong; she's missing her entrance and flubbing her song.

Fernando can save her-but only if Delores behaves. Will Delores hit a sour note? Or will she team up with Fernando . . . and bring down the house?
