Book excerpt: Bitty is a canary whose courage more than makes up for his diminutive size. Of course, as a miner bird who detects deadly gas leaks in a West Virginia coal mine during the Depression, he is used to facing danger. Tired of perilous working conditions, he escapes and hops a coal train to the state capital to seek help in improving the plights of miners and their canaries. In the tradition of E.B. White, George Selden, and Beverly Cleary's Ralph S. Mouse, Madelyn Rosenberg has written a singular novel full of unforgettable characters.
