When I went to barns and nobles I got the third Vampire Diaries the Return: vol.1 Nightfall. In this book Stefan brakes up with Elena to become a human again so that he doesn’t change her.So he leaves Elena so he doesn’t change her. So he trusts his older brother Damon with the responsibility of taking care of Elena. So Elena is so depressed that she goes to find Stefan her one and only love. I want to tell you more but you’re going to have to read it yourself. The next book is the vampire dairies the return: vol.2 shadow souls not yet in the library at all. Hope you enjoy.
