Savannah would be happy spending the summer working at the library and reading. But then she meets Jackson, who Savannah's convinced is the one. At first it looks like she's right. He abides by her mama's strict rules and stays by her side when she is hospitalized for severe asthma, which Savannah believes is improving only because Jackson is there. But when Jackson is called away to help his family, Savannah has to learn to breathe on her own, both literally and figuratively.
