Hopeless, by Colleen Hoover from Best Young Adult Books of All Time

What it's about: Seventeen-year-old Sky knows Dean Holder is trouble the moment she meets him, but he also sparks new, exciting, and sometimes scary feelings in her. When she gives in to the attraction she tries to deny, she learns that he (and she) are nothing like what people think they are. Top quote: "The sky is always beautiful. Even when it's dark or rainy or cloudy, it's still beautiful to look at. It'll be there no matter what, and I know it'll always be beautiful." Goodreads rating: 4.39/5
