This is also a story about love and how far you are willing to go for it. Some of the characters are forced to watch people they care for deeply slip beyond their grasp, and in some cases turn into monsters, even if those monsters have a vague memory of who they once were. As Mel navigates the new world that’s opening up for her, she realises that she’s going to lose some things even as she gains others, and that love can come with a sharp cost. And may, sometimes, involve compromise and a willingness to rethink your assumptions and change your attitudes. If she truly loves Cathy, that means sticking with her through thick, thin, and vampire.
