At first, I couldn't figure out how this book and the Percy Jackson books were connected. Sure, they talk about Camp Half Blood and you get to see some of the characters from Percy Jackson. But, there was a disconnect for me. The more I read the book, the more I felt a disconnect. I knew that Percy was missing and Annabeth was looking for him, but it seemed to me that the previous series' characters made only brief appearances and I was kinda bummed out about that. I wasn't disappointed with the book, that's for sure. I just couldn't quite get over this feeling of disconnect between the two series.
HOWEVER, it wasn't until about the last chapter, that the author finally came out and defined the distinction between the two! I felt like a serious idiot when I realized that he'd been saying it all along, I just hadn't caught on.
So, without giving anything away, I will tell you that if you pick this up and start reading and you feel a disconnect, don't quit reading it! If you're faster than me to get it, awesome (just don't tell me so I don't feel like an even bigger idiot! ;) )
And now, I must wait until Spring to get the next Josie Kilpack book, Fall to get the next book in this series, and I'm not sure about when the next one in the Kane series will come out. I guess I'll have to keep digging through my pile that I've collected but haven't read!
