Cyn is a regular behind the scenes girl who's totally crushing on Ryan. She's obsesses about his every move in the way only a teenage girl really can. She's teased mercilessly by her bestie, Amy, who's never really had a big crush like this before. That is, until the new librarian shows up. 
 Amy quickly finds her very first crush and Cyn jumps on the chance to tease her friend back. It quickly loses it's appeal, though, when Cyn realizes there's something wrong with the new librarian, and that Amy's in trouble. 
 I feel like if you've got to throw romance into every YA book this is how it should be handled. Not, "omg, I shouldn't even be thinking about this, except I am, because I love him, even though I was told not to trust anyone, I can trust him, I can tell", but instead, along the lines of "shut up nerve endings, isn't it good enough that we're sitting in a dark closet with him, is now really the time to be worrying if we're touching?" And oh how I love Cyn and her silly nerve endings. 
 There were some pacing discrepancies here, where everything is happening, and then nothing is happening, and then maybe something is happening, but we can't really tell yet. That being said, I didn't always mind the down time in between the demon encounters. I liked hearing about how Cyn felt, I liked getting to now all of her character and not just the action packed bits. I would have enjoyed a little bit more "action" with Ryan, but that's only because I found his character kind of dull, and thought it might liven him up some to have him actually doing something. 
 I'd suggest reading this one in as few sittings as possible to avoid getting bogged down with the slower parts, because once you push through, it really grabs you. It's worth it, I promise.
