This one had a few glaring problems. There was some good- the writing was on par with the rest of the series. Reading about the girls getting dressed for battle was fun, mostly for nostalgia. I did like Kendra and Catty's relationship, it was obvious that Kendra really cared about Catty and would do anything to protect her.
So, on to the problems.
Toby is a great big red flag to me as a reader. After reading about the way the Regulators cause static build up and then all of a sudden they get shocked around him... gee wonder what he could be?
It seams to me that Catty most of all should have realized something was going on with Vanessa. They have been friends for a very long time, and the other girls should have realized it when she was not wearing her amulet. It's made such a big deal of in previous books about the amulet being able to warn them, and none of them thought to get some time alone with Vanessa to ask her when hers started burning or anything? It's a big step back from previous books, as the girls are also usually a lot smarter.
Jimena can't control her premonitions, but they do come when a big run in with Followers is goanna happen. Why would a Regulator kidnaping Vanessa be any different? In fact, Jimena has almost no premonitions in this volume.
Serena can read minds for Pete's sake. She read Catty's mind to understand what a Regulator felt like when near. She felt none of that from Toby? She did not once look into his or Vanessa's mind? I would think that Vanessa would have in her subconscious that Toby made her uncomfortable, and Serena could have found it easily had she glanced at all.
The last thing that bothered me was Catty can suddenly go back several weeks with her power. In the first book, she does talk about leapfrogging back, but can only do it about twice, so two or three days. There is no real explanation of how she suddenly is able to go back weeks.
Over all, this is a interesting premise for a series and it is pretty well written. After the first book, though, things are just washed and repeated. There may be new villains who come in, but it's basically a mystery comes up centered around one girl, she tells the others, they go to school, Planet Bang, hang with their boys, usually one of which is on the Atrox's side, then they schedule a showdown and get dressed up for it. Then they win the show down, yay!
There are some variances, but that's it in a nutshell. It's a quick light series that teens can fall in love with (I did) but will probably leave adults wanting a bit more.
