A band of family pets secretly embark on a mission to find a fish that has mysteriously disappeared in this illustrated middle grade tale of family and friendship.

When Lillian turns six, her favorite gift is an extraordinary fish whose body shimmers with all the colors of the rainbow. But when the brand-new birthday fish disappears, Lillian is devastated.

While she and her brothers try to unravel the mystery, the other family pets―the horse, the goat, the dog, the cat, the turtle, the spider, and the bird―secretly band together to find out what has happened to the little fish. A trail of clues soon leads the animals on a fantastic adventure along the river and deep into the woods, where they encounter new places and strange creatures.

James Menk's delightful, lively tale of discovery and friendship will enchant readers of all ages. Louisa Bauer's captivating drawings bring this charming story of children and their pets to life.
