Harper and the scarlet umbrella / Cerrie Burnell ; illustrated by Laura Ellen Anderson.

Enhanced descriptions from Syndetics:

Once there was a girl named Harper who had a rare musical gift. She heard songs on the wind, rhythms on the rain, and hope in the beat of a butterfly's wing.

Harper lives in the City of Clouds, an enchanting place where it rains every day and an umbrella is always a good idea. With her Aunt Sassy, her beloved cat, Midnight, and all of her neighbors in the Tall Apartment Block, every day is full of possibility.

But when every cat in the city goes missing--including Midnight--Harper is determined to find all of the precious pets. And she'll need a magic, flying umbrella to help in her search. Recruiting friends from her building to help, the magic umbrella whisks them into the sky on the trail of the cats and adventure.

They stumble on the Midnight Orchestra--tabbies on triangle, Siamese singing, Persians on piccolo--all under the direction of its fearsome, wild conductor. But can the group use their talents, quick thinking, musical skill, and a little magic to stage a rescue like no other?

Harper and the Scarlet Umbrella is a spellbinding tale of friendship, music, and magic featuring a diverse cast, brought to life through stunning illustrations. A perfect book to be shared and treasured.
