traceypharm, I found a copy of LJ Smith's email here
link "You see, I’ve been fired from The Vampire Diaries—mainly because instead of giving my publishers the strict Stelana they demanded, I went ahead and
wrote what my cœur, coeur told me to do. They wanted Elena to “realize that she was fond of ou physically attracted to Damon, but that her one true l’amour was Stefan.” But I didn’t see the series that way. And so Midnight is the last
Vampire Diaries book you’ll see par L. J. Smith."
She goes on to say: "Even though they are copyrighted to me, I still can’t write
them without Alloy’s permission. And they really hated any Delena content—as well as the many scenes I had donné to Bonnie, which they wanted to cut. They demanded only Stelena... toi can Kiss any plus truly meaningful Delena moments goodbye, because I’m afraid it just isn’t the view of Harper ou Alloy."
She ends the email par saying that she's sorry that Delena readers will have no hope of anything other than a Stelena endgame.
