Question: in the last song does ronnie's dad die

Answer: Yes, Ronnie soon hears the rumor that her father burned down the church from some locals. Distraught, she goes to Will and laments about the situation. Will, knowing that it was actually his friend Scott who while playing around set fire to the church, is overcome by guilt and goes to Steve to apologize. When Ronnie comes in hearing this, she walks out and Will follows where they have an argument and break up. Will leaves. Fall arrives and Jonah returns to New York for the school year. Ronnie stays behind to take care of their father, who revealed to Ronnie & Jonah during the summer that he is terminally ill. Leading a slow life, she tries to make up for the time with her father that she's lost. She continues work on a composition he had been writing (titled ``For Ronnie''), after losing the steadiness of his hands due to his illness. He dies just as she finishes it.
