And of course, if you’re talking about influence, Libba Bray’s Gemma Doyle Trilogy/AGATB is clearly inspired by the movie. Some of the differences include the ending, the period and country and the part where they go to a Catholic school. But the personality makeup of the group is nearly the same.

One girl's wish to be beautiful, red hair for the actual "gifted" one, the echo of the phrase "tricky, tricky", yadda... But the most interesting thing for me was how Libba tossed the ending out of the window. Sarah just can't be friends with the girls once they'd done that to her: Gemma, by contrast, is all forgiveness. Over and over again.

Why do you think Libba changed it that way - to argue that the best people forgive, or only "suckers" forgive? ;)
