Between the lines / Jodi Picoult and Samantha Van Leer.

What happens when happily ever after...isn't? Delilah hates school as much as she loves books. In fact, there's one book in particular she can't get enough of. If anyone knew how many times she has read and re-read the sweet little fairy tale she found in the library, especially the popular kids, she'd be sent to social Siberia forever. To Delilah, though, this fairy tale is more than just words on the page. Sure, there's a handsome (well, okay, hot) prince, and a castle, and an evil villain, but it feels as if there's something deeper going on. And one day, Delilah finds out there is. Turns out, this Prince Charming is real, and a certain fifteen-year-old loner has caught his eye. But they're from two different worlds, and how can it ever possibly work?
