If you're a Sigler fan, odds are that you'll like this. My review is mostly aimed at the fans of YA fiction, which this book technically falls into. Technically. Our protagonist is an older teenager but it's not really new adult territory since Savage is mentally younger than her body looks, so there's not really any of the hubba hubba romance that you'd see in a new adult book. I also need to note that this is the first time that Sigler has written something like this. He does have the teen version of the Galactic Football League, but it's not really in the same (foot)ballpark as this read is and this is also the first book he's written that is entirely from a female teen's perspective. (Pandemic was partially told from the viewpoint of an adult woman, but not exactly the same thing.) 
 The purpose of that long preamble/disclaimer is to let you know that this is brand spanking new territory for the FDO (Future Dark Overlord as we fans call him), so while he does a fairly good job of trying out something new there are a few stumbles here and there. None of them are major enough to where they'd ruin the read for anyone but I know that a lot of YA readers will probably notice these more or at least a lot faster than people who aren't big readers of the genre. 
 Anywho, on with the review. There will be some very minor spoilers but they are not the major spoilers, which Sigler has asked that we not share. That's fair enough since I didn't have any issues with the twists. They're not entirely new to this type of read but they're novel enough that I didn't really see everything coming from 10 miles away like you get with some YA books. I chalk this up to the fact that the FDO has so far pretty much written for adults and as such isn't really into some of the pandering that you can get with YA books where they dumb everything down in favor of focusing on the romance. 
 Speaking of romance, that's kind of what I liked about this book. There are some twinges of romance here and there, but by large this was just our main character Savage reacting to all of the new hormones surging through her body. She reacts to all of this with a large dose of bewilderment since the last thing she knew, she was at an age where boys weren't objects of affections in that way. I kind of liked that since it was a nice touch and very, very refreshing from the usual insta-love you typically get in YA fiction. 
 The pacing in this is pretty well done and while it's not non-stop whizbang action, there's enough here to where it'll keep you occupied nicely. I absolutely loved the technology in this and how it's approached by Savage and the others, who are almost completely ignorant of how everything works. They figure some things out as the book progresses, but this ignorance helps fuel the suspense along so that the big reveal is a little more neat. 
 The only slight quibble- and it is slight- is that at times I got that "stranger in a strange land" feeling with Savage's character. Basically, it's just that at times Savage sort of put off the "this is a female character as seen by a male writer" vibe every once in a blue moon. It's nothing that ruined the character and honestly, I think that I'm so used to female YA characters being a certain way that it may just be that she doesn't fit into the genre stereotype. 
 Overall this is a great read and one that I finished in a day. Any rough spots are very minor and to be honest, it's exciting to see Sigler go into this field. YA fiction is dominated by authors who write books that are aimed at young females and this is a book that could easily appeal to younger male readers, who are woefully undertargeted in this genre. If this is him taking his baby steps, I can't wait until he starts sprinting in the next book. Well worth buying.
