Billie Holiday-also known as Lady Day-had fame, style, a stellar voice, gardenias in her hair, and lots of dogs. She had a coat-pocket poodle, a beagle, Chihuahuas, a Great Dane, and more, but her favourite was a boxer named Mister. Mister was always there to bolster her courage, even at her legendary appearance at New York's Carnegie Hall. Stylish illustrations keep the story focused on the bond between Holiday and her dog. An author's note addresses the singer's troubled life, and includes a little-known photo of Mister and Lady Day!
