What We Left Unfinished.

Caroline thought that chapter of her life was over. She was wrong.

After a violent attack on her home, Caroline is thrown back into Klaus Mikaelson's world when enemies from his past return with a dangerous interest in her.

But this time, it's not just about Klaus.

It's about her name written in places it should have never been, secrets buried long before either of them realized, and a man tied to a forgotten experiment who seems to know exactly who she is.

As old feelings rise back to the surface and the line between danger and desire begins to blur, Caroline and Klaus are forced to face everything they left unfinished.

Because some stories don't stay buried.

And some people never really let each other go.
