Yes I’m posting about this whole Day Watch thing again. But look at it this way, you won’t see any more posts about it for a while for two reasons: One, I’ve already seen the movie and posted about it. Two, now that I’ve read the book, after this post all I will be posting about is the book Twilight Watch, which happens to be the third and final book of the series. 
I don’t really have anything to say other than if you liked the moves and or the first book, the second book keeps the same pace and has the same O-M-G plot-twists in it that one comes to expect from this series. In a similar vein to Night Watch, Day Watch is really three different stories within one book. Whereas Night Watch was all about the stories of the “good guys,” Day Watch isn’t so much about the “bad guys” as one might imagine. Ambiguity seems to be the key. If you’re interested, grab a copy
