A Goodreads user asked Laura Thalassa:

Hi there! I really enjoyed reading pestilence ,thank you for writing it❤ the only thing that bothers me is that Sara ages and Pestilence doesn't. Before the book finished I thought that ether Sara would've become Immortal or pestilence mortal (and I was glad the latter didn't happen.I couldn't imagine Victor as mortal) but neither happened so for now I'm lying to myself that Sara doesn't age.Am I too delusional?xD

Laura Thalassa I deliberately didn't answer the questions of Pestilence and Sara's mortality/immortality in the first book of the series. There's still more of the horsemen to be revealed, and you'll see more answers to these questions in the upcoming novels.
