A new spin on the familiar fable. A mouse couple living in a town are enchanted by the simple life of the country, and, while on a picnic, meet a pair of local mice who long for the luxury and convenience of the city. Homes are swapped, but they find that reality is different from their expectations. Both couples end up fleeing from unfamiliar, predators-a cat in town and an owl in the country-all the way home. The owl and cat collide, and in an original twist, negotiate a territorial swap of their own.

Traditionally, the town resident is portrayed as a pompous snob who turns his nose up at the country dweller's simple fare, while the country mouse is a folksy bumpkin. In Brett's version, the town mice are as charming and naive as their country cousins. Furthermore, the original fable depicts country life as utterly tranquil, but the city mice find that it is anything but serene.

Brett's narrative alternates the parallel mishaps of the two sets of mice with lively, smooth writing and a deft touch of humor. As with any of her books, the illustrations are rich with meticulous detail. The natural fibers of the clothes of the country mice are as realistic in texture as the fine beaded and bedecked clothing of the town mice.
