Solar is in her last year of high school and is reeling from the recent death of her grandmother. She has abandoned her plans for the future and fallen in with a bad crowd. Her little brother Fenn doesn't understand why she's changed -- she doesn't even want to help him build their rocket in the garage anymore. Campbell is a tin woodsman -- a clunky metal man whose sole purpose in life is to chop down trees. He longs for more, however, and decides to seek out a heart, believing that, with one, he will be able to feel things he has never felt before and, therefore, change his life.
