Thus we concluded the Midnighters trilogy, where more secrets are unearthed and the inevitable resolutions are commenced. And I've got to say, it ends rather well. Not that I'm going to tell you about that (you're going to have to read it). But I'm getting ahead of myself. 
 Not only are the midnighters trying to figure out things in the blue time, now this time comes randomly in the middle of the day. They have never witnessed their midnight at any time other than, well, midnight, and their lore says nothing about it. This brings them to discover a history that had been long buried, and the truth behind the midnighters of yesteryear. 
 What makes it really interesting is Rex who, previously, was transformed into a half human/half darkling being. Though he's been rescued from his halfling fate, part of his mind is still darkling-controlled. He knows & feels things that his fellow midnighters do not, a knowledge only known to the creatures who inhabit the midnight hour. 
 Rex makes this story. The other four midnighters have hardly changed at all (Jonathan has only grown more annoying), and he's the one who has really developed as a character. Of course, if Rex didn't have a darkling mind, the conclusion would have been entirely different. It's his insight into their minds that aids in their journey of understanding. 
 Much of the action is the same as the previous two books--gathering and naming weapons; fighting off creatures in an elaborate, impressive manner. It was the conclusion that really made the story interesting. And, like I mentioned earlier, it was good. Totally unexpected; both bizarre and interesting. 
 I didn't enjoy this one as much as the first two books, but it's necessary to complete a trilogy. If nothing else, it finishes things off in a neat little package. I certainly won't complain about that.
