Okay so I have now read this series and have some observations, SPOILERS AHEAD. This will also be a list/ramble type review, my apologies for the chaos.
1. No one in any of these books has a lick of sense. They stumble around filled with false bravado, the bad guys are sloppy and stupid, the good guys are oblivious and stupid. And everyone consistently makes the wrong choice, and that is how the plot moves around. Everyone trusts too easy, lies at the wrong times, and I could feel the desire to strangle half the characters.
Red flits from being psycho and overconfident, to whiny and helpless. Hunter is all alpha-male, but then leaves her to go deal with his clone family (2nd book) which seemed contrived as all hell. Rapheal falls in love with Chaos in about a second, and everyone is concerned but not concerned enough that creepy Michael Travers, who is now insane, won't double cross them.
Chaos is an annoying character with a cool ability she does not use nearly enough, and she also is damselly, a half wit, and also not that likeable. Demery could have resolved a lot of issues if he had just told the truth, and Morgan would not get kidnapped if he did not fall for a ruse that Bugs Bunny has used.
2. So we are in the future. And it's all post apocalyptic, and I like that. But then it's killed by everything being called synth-beer, and synth-paper. You build a future world, fill it out more. I like the dome lives, and the water's sparseness, the hovering cars and all of that. The gritty desert landscapes. it's interesting, but I feel like the author did not throw herself into the world building as much as she could have.
3. It is apparently very easy to go back and forth thru no man's land. Also relatively easy to survive there, even the bad guys are fairly hospitable.
4. The sex is pretty good and pretty hot, but I wish there had been a lot more time with everyone roughing it out in no man's land. And what it really means to be an Unknown and all that, instead of constant humping on the part of Chaos and Rapheal,
All in all she is not a bad writer, and has some interesting ideas that make her work memorable in such an oversaturated genre. It is just frustrating when I see potential to work with some really cool, really unique ideas, and they don't live up to it.
