The Summoning is a really good start to a creepy series. Although, I don't agree with a lot of the quotes of people saying it'll give you nightmares, make you scream, and creep you out until you look behind you; this book didn't really creep me out. I guess I need something scarier for that to happen. Plus, not a lot of things that would seem scary, such as Chloe communicating with and seeing the ghosts, happened until close to the end. I think it did take a little longer than necessary to get to the point, but when the plot finally started to pick up, I enjoyed the book so much more, and I really want to find out what happens next. 
 Even though this book is a little low on the scare factor for me, the overall story is enjoyable and well-written. I like build up between characters, and this book has that without going overboard. Speaking of characters, I find almost all of them to be likable, except, of course, for the ones trying to cause serious trouble, but all of them contribute to the story. There is little to no romance in this book. The possibility of romance is touched upon, but it's not actually there, at least not yet. I appreciate that, because, as I stated, I like build up. I don't care for love stories involving "love at first sight," "you had me at hello," "the moment I saw you," "you've completed me from day 1," "I belonged to you from day 1," I could go on and on. None of that is realistic to me, and I don't care to read about it. So, if there is romance in the next two books, and any characters involved say any of those things mentioned above to their partner, I might be a little irritated. 
 There is a cliffhanger being as this is the first in a series, but it's pretty subtle and nothing really crazy. Of course, it revolves around a particular character that I love, so it did make me a little bit crazy, but if any readers don't care for that character, they'll probably be able to handle it.
