Make the book "Frozen Charlotte" into a movie

I love the book "frozen Charlotte" and I think it should become a movie! It is a ghost story book- back cover overview ~

When her best friend dies under mysterious circumstances, Sophie sets off to stay with her cousins on the remote Isle of Skye. It's been years since she last saw them--brooding Cameron with his scarred hand; Piper, who seems too perfect to be real; and peculiar little Lilias with her fear of bones.

Still, Sophie never expected the strange new rules the family now lives by: Make no mention of Cameron's accident. Never leave the front gate unlocked. Above all, don't speak of the girl who's no longer there, the sister whose death might have closer ties to Sophie's past --- and more sinister consequences for her future ---than she ever knew.
