Takedown

If the creatures die from sunlight exposure, why aren't we seeing that used as a weapon? I'd suggest punching holes in walls and roofs, using mirrors or metal reflectors to light a lobby further, perhaps using a prism or disco ball to spread the light through a room. Haven't seen anybody using a generator with ultraviolet lamps to clear out a building. The author has made it clear that Jack believes that sunlight would be torture, but certainly some of the groups he met would have no such compunctions. From the foreword of the next book, I see that the creatures wouldn't be susceptible to commercial UV lights or grow lamps, but none of the characters in the series have even tested UV lighting, so how would they know? As I see it, the creatures are fighting a losing battle. The environment itself will kill them in minutes if their shelter is compromised. Like the classic vampire, this monster has fatal flaws that should prevent it from dominating the world.

There a handful of errors that should have been caught by the editor. For instance, a physicist is not the same as a physician.

The writing style seems designed for a television miniseries - with lots of descriptions that are meant to be developed into computer generated graphics as done by the CSI series. In my opinion, each book should be able to stand alone as a story, and not end with such an obvious cliffhanger.
