After Diana absorbed the Book of Life, many fans questioned if that would mean she is now immortal like her vampire beau. Though this is not disclosed in the book series, Harkness addressed the question about Diana's mortality and Matthew's immortality during a fan Q&A.
While some fans have theorized that Diana may have created her own immortality spell to live out her days with Matthew, Harkness confirmed during the fan event that she will eventually die. "Shes mortal and a warm-blood, and not going to have an extended life," Harkness said.
The author added, "Matthew has an extended life, and I think, again, the sad truth is none of us really live forever, and we all have to make the best of what we get handed. So I think thats a really normal part of life. One of the things we need to do better maybe in our time is learning to say goodbye, and learning how to live without the kind of regrets."
