There's something very strange about the rats living under the rosebush at the Fitzgibbon farm. But Mrs. Frisby, a widowed mouse with a sick child, is in dire straits and must turn to these exceptional creatures for assistance. Soon she finds herself flying on the back of a crow, slipping sleeping powder into a ferocious cat's dinner dish, and helping 108 brilliant, laboratory-enhanced rats escape to a utopian civilization of their own design, no longer to live "on the edge of somebody else's, like fleas on a dog's back."

This unusual novel, winner of the Newberry Medal (among a host of other accolades) snags the reader on page one and reels in steadily all the way through to the exhilarating conclusion. Robert O'Brien has created a small but complete world in which a mother's concern for her son overpowers her fear of all her natural enemies and allows her to make some extraordinary discoveries along the way. O'Brien's incredible tale, along with Zena Bernstein's appealing ink drawings, ensures that readers will never again look at alley rats and field mice in the same way.
