For chapter two, the major details are more than just the headings to those sections. It's important to make it clear to your reader what it means if it's scary be wary and so on. Otherwise they are left to figure things out on their own. In a sentence, for each of the warning signs, make it clear what is important about those warning signs.

For chapter one, pretty much the same thing needs to happen, based on the bold section headings if nothing more. This is the sort of thing the directions tell you to look for and it's for good reason, because it will provide you and your reader a clear map of the original if you follow it. Bradley

This summary sounds more like a conclusion to a paper because you are writing as if your audience has already read the chapters and you are referring back to them. I think you have a good start with your information and the main points.

You have a good beginning! I also think you identified major points very well but I would just write those main points in complete sentences.

You have the beginnings of a good overview. I think we are supposed to elaborate a little more on each point though. Giving examples of each item you listed without going into minor details would help with the next part of the assignment.
