Need a palate cleanser from The Last One

I read Alexandra Oliva’s The Last One as I’ve seen it recommended here before. I’m very mixed on how I feel about it. Love the concept but I felt the execution was only ok. Or maybe I just really liked everything except the main character. She really annoyed me. Please suggest some other “end of the world” type books. I’ve read The Stand and consider that up there minus the ending (but I’m almost always underwhelmed by a King ending unless it’s a short story), as well as the Silo Series to give you and idea of what I’m into.
