Thanks to Bella's comparison of the co-dependent Bella/Edward death-dance to the Heathcliff/Catherine co-dependent Yorkshire moor grudgematch sales of Emily Bronte's only novel are skyrocketing according to The Telegraph.
Apparently sales have quadrupled in the last year. Who'da thunk? I don't mind. Wuthering Heights is one of my favorite novels so if one book character inspires teens to read another book (especially one I think is fantastic) I don't have a problem with that.
I do have a problem with the Twilight tie-in marketing.
I was a pretty advanced reader as a child and read Wuthering Heights for the first time in my early teens without too many problems (the first edition I read may also have been abridged because on a re-read I realized I didn't remember much religious grumbling). Some teens don't read at an advanced level. I've had tweens and teens come back to me, with this edition, complaining that they have no idea what is going on in Wuthering Heights - the language is hard for them to understand. I'm usually able to keep them from hating the book by giving them a leg-up summary and the Sparknotes website to help with the ramblier aspects of language and plot.
I really do like how HarperCollins is introducing readers to great literature - the other tie-ins include Romeo and Juliet and Pride and Prejudice - but I think these editions do young readers a disservice. They need the extra information to make the leap from Twilight to the 1800s and beyond. I regularly point readers to Barnes and Noble, Penguin, Oxford, or Norton editions of Wuthering Heights because I think those editions will help younger readers (and older, too, if they don't regularly read non-21st century books) through the rough bits; they may not have slick red and black covers but the additional information is a definite plus.
