The book continues with the story of Dan and Holly. It started out good but went downhill from there with the books main characters making the stupidest decisions. Example, there’s only three of us and we need to go fight off at least a dozen people, what shall we do with the hostage? Here’s an idea, Dan will stay here and guard the prisoner for no reason while Holly, you go down there and fight all of them and take Bird along, the person who has zero experience in guns or fighting.
They also supposedly live in a very secure building yet somehow always seem to forget to lock the doors.
Just a few examples of why this story falls flat.
