3.5 stars for this one. The story was thrilling, I was up all hours of the night reading, and the twists and turns kept me on my toes. The only thing is that I didn't like the protagonist! Not necessarily unlikable, just written weakly.

A high 3 stars, but not enough to make me round up.

Really liked the concept, writing, and story, but felt unsatisfied with the execution. I guess I just wanted more of the story and thought it was incomplete when it ended.
