On the night called Guy Fawkes, a special puppy is born. She is a New Zealand Huntaway dog, and she loves to play with her sisters and brothers. Then she is adopted by a tall woman, who calls her Tanna and works with her in obedience and agility class. But her leg hurts when she jumps, and the vet discovers she has a deformed hip. What will Tanna's owner do? Danny is a young boy who also has a hip disability; his leg hurts when he tries to run and play with other kids, and he has been to the hospital many times. He works hard to strengthen his muscles—just like Tanna does—but eventually he has an operation; Tanna may have to have an operation as well. One day, Danny meets Tanna and her owner, and they each learn that everyone can be good at something. This children's book tells the stories of a dog and a boy who were both born with hip problems and shares the lesson they learn together.
