The Mark - Jen Nadol This was a very interesting premise, I have never read a book with this topic, it was very poignant, and made me think hard about what I would do in Cassandra's situation!Cassandra's life was very interesting and it seemed that everything that could happen did, which was a little hard to believe but painted a good scene for the novel. Her personality was very relate-able, and I really felt what she did. Jen really developed very interesting characters.This book kind of made me squirm when she was in her relationship, but besides that it was very good. The only main problem I had with it was the fact that it just cut off, I wished the ending could have been less of just a cut off, even though there is going to be a sequel.
