Sal and Charlie are married. And Sal can never leave Charlie, no matter what.
Everyone says to go into this book without knowing a whole lot about it. I did just that. It was disappointing and boring. The writing was too simple and it made the story fall flat. It was too repetitious. I did like the twist. Kudos to the author for creating a character I absolutely HATED! There were a few times I almost stopped reading because of Charlie.
