I've read a fair bit of apoc-fic recently & some of the tropes are starting to feel a little stale. And the premise of this one is also far from original - last person left alive, doing what needs to be done to survive. It's the relationship between Mother & Monster that kept me intrigued. The dual narrative didn't work well, Monster's POV being less engaging, the character being less developed. And some of the events were less than convincing.
