Beatrice Corwell has a crooked haircut, eight well-trained cats, and a plan: she's turning herself into a Tin Man. Once her heart is made of metal, she'll no longer miss her beloved dead grandma, her absent dad, or her recently moved-away best friend. While Beatrice awaits her transformation, she keeps vigil with a special doll and a handful of wishes she's determined to make come true. With her encyclopedic knowledge, there must be a way to grant her heart's deepest desires. When an unusual boy named Caleb moves to town and mentions his granny's interest in magic, Beatrice decides to enlist their help. She quickly learns, however, that spells don't always go as planned, and witches can't be trusted. With the arrival of an unexpected visitor and a series of otherworldly messages, Beatrice's plans begin to falter. Will her heart turn into metal? Will any of her wishes come true?
