Presley Mackenzie knows she’s not supposed to fall for her best friend. She really shouldn’t fall for him—especially since he is her ex’s brother. It doesn’t matter that her ex cheated. It doesn’t matter that she was the one to walk away. She’s not supposed to fall for her best friend. Even if Mason Sutton is the only one who can make her smile or laugh or feel like being herself again. She’s not supposed to fall. Until she does.
