I’ve read and listened to do many apocalyptic stories that it’s getting hard to find any me ones that are original. when this one introduced the AI component I was worried I’d have to ask for a refund. I thought it wouldn’t be realistic enough. I couldn’t have been more wrong. the story is very character driven and it’s has a lot of characters. each person has distinct personalities that grow and change and work together to make this a story I couldn’t put down.
