L. J. Smith said she wanted The Hunters: Moonsong to be about the group going to Dalcrest College. Damon would help Meredith to control her bloodlust, although that seems to have been resolved in the ghostwritten books. In an e-mail, she mentions her planned plot for The Hunters: Moonsong.
As for The Hunters:Eternity, "I even had the last book in that trilogy plotted out, where Stefan’s worst nightmare comes true and he takes so much blood from Elena that she has to be taken to the hospital for a massive transfusion. He then decides to Influence Elena so that she will forget his existence, and he does so, to Damon and Bonnie and Meredith’s consternation. I wanted to show how this affected each one of the characters, and how Bonnie once again begins to write in her diary, since Elena’s diary is also forgotten, along with Stefan. I like to write things from Bonnie’s point of view, as I did in Dark Reunion. But none of these things will happen, because I won’t be around to write it."
