Looking for a title

I loved this movie so much, can't remember its title or names of the actors. It's about a girl who works taking care of an old lady who dies. Then she finds a job working for a grandfather whose daughter died in a boat accident. Now her granddaughter is living with him, he blames his stepson, who has problems with drugaddiction for the death oh his daughter. A romance starts berween him and the new employee. Very beautiful movie, can anyone help me with its title? It's an american movie. Thank you so very much!
