The male and female lead are possibly half-siblings.. Watching the new show, they push these two together quite often, heaping on romantic tension. As someone who hasn't read the book and only the saw the movie, I'm interested to see how this dynamic will change once that implication comes into play. The show is typical ABC Family (I'm sorry, FreeForm) teen drama fare, but with an established storyline, can it go on, flirting dangerously with the idea of an incestuous relationship? Or will the show deviate for the book plot? I guess we'll see.
