My big problem with this book was Martin. Why did he need to betray Susan and Harry at the end? He seemed to be betting pretty heavily that Susan would kill him, which only happened because Harry manipulated her. And, man oh man, do I hate that Harry did it. That he had to do that. But, in that situation, there was no other option.
It was so heartbreaking that he killed Susan too.
But, wouldn’t Maggie have died too? She was Susan’s child after all.
