In this loving valentine to life in the theater, we join a delightful cast, follow a daring adventure, and welcome a brave new hero. This delicious tribute to the Broadway musical is written by two bestselling authors who have firsthand experience of this much-adored world.

In the heart of the great metropolis of New York City, the bright lights of Broadway shine. And down, down, down, beneath a theater known as the Sovereign, there sits a long-forgotten architect’s model—the Sovereign’s miniature replica.

In this secret space, an adorable troupe of theater mice busily prepare to stage their own show, Broadway Airs. Among the cast and crew are Emil, the director; Harold, the character actor; Adelaide, the diva; and young Pippin, the intern. Rehearsals are in their usual state of chaos when suddenly the production is threatened by the imminent demolition of the theater and the devastating disappearance of Adelaide.

As the clock ticks toward opening night, everyone is worried. Will the little Sovereign survive? How can they pull off the most important night in mouse theater without their star? Somehow, the show must go on!
