I really enjoyed the medium used to convey this story. I was worried about having dual authors, but thought the overall story was cohesive and entertaining. It has been really interesting to read a story that is so heavily centered around the plot (independently) and the romance (catalytically), while leaving the reader...unsatisfied? *spoiler* We never get to see our romantic heroines interact in person for more than a page, and I found that deeply disappointing. But it was also a nice change from the "in you face we fell in love in five seconds" romances portrayed in most YA novels... I'm so torn!
