This novel was more romance-centric than the previous two. I feel that a romance like this can only carry a series so far and there has to be more story beyond that in order to keep my interest. The story on the Lux / Arum did not progress very far, and took a backseat to Daemon and Katy. I wanted more on the aliens! It will probably please a lot of Daemon / Katy fans, and teenagers, but it's just not really my cup of tea.
