I'm going to be honest here. I did not really get into this book until the last third of it or so. The rest of it just didn't hold my attention for some reason. However, that last third was so good that I am determined to continue reading this series.There are several things I appreciated about this story--its premise, the focus away from the usual vampires and fairies while still being paranormal, the dynamic between the "troubled teens" and the Lyle House employees... At the same time, I found it rather unbelievable that Chloe would not realize or would simply deny that she was seeing ghosts, when it was pretty obvious what was going on. Overall, the characters could have used a bit more development, though obviously some were fleshed out more than others (Chloe and Derek, for example). The writing is generally good, though at times I found myself wishing it was more descriptive and captivating.What really saved this book for me, though, was a big plot twist towards the end. Honestly, I never get tired of them although I know some people do. And with The Summoning, I really didn't see it coming. By the way, I should mention that I regret not having The Awakening right here to start, as the first book does end with quite the cliffhanger. All-in-all it was a pretty good read (not great, for me) but I see a lot of potential and I hope to pick up the story again soon with the second book. One other random note: I really love the cover of this book!
