Alex:
I think it's good that you give a setting to the story and sum up what happens (or has happened) in the beginning, so the reader has a basic idea of what the story is and what to expect. It's also good how when you talk about reasons for teenagers to read the book, you back it up with evidence and comparison to real life.

Melissa:
I agree with the previous comments on the TAGS, but othwer than that, it's a good post. The TAGS though is just the main thing, so make sure you add a descriptive one.

Roksor:
I think this is a good book review, but it could be helpful by putting the question down.
