Theme and Summary- The Last Song

This book is about a girl named Ronnie who is facing many problems with her life currently. When her parents divorce, she is separated from her father, and isn't close to her mother. She is forced to go to her father's house for the summer, along with her brother Jonah. As Jonah is excited to see the beach, his father, and the life around where he lives, Ronnie is desperately trying to find a way to get out of the situation. When Ronnie and Jonah arrive, Ronnie avoids her father as much as possible, while Jonah spends every second possible with his father. Later in the story, Ronnie meets a guy named Will, and falls in love with him. She is struck with a hardship among her family, and goes to him for his help. He helps her and Jonah to try and get through the situation but suddenly she doesn't feel like will ever again. I think the theme for this story is, always cherish what you've got because when its gone, you will have wished you did.
