While I found it interesting to see Bobby/Robert from the eyes of a different character, those eyes were incredibly boring ones. Gwen was a flat character in a flat book serving as filler. The sole purpose of this book seems to have been the introduction of William. If the series continues, it'd be good to see Gwen again and have some growth for her character, but as the series stands so far, she seems pointless. This whole book seems pointless. Bobby and Alicia's story could have moved along with the first and third books alone. The very existence of this book makes no sense. I don't have much else to say--boring book, boring characters, the reappearances of Bobby and Alicia were the only reasons I kept reading.
