I really enjoy the world in this series, and I'm intrigued by where Tyler seems to be driving the action. I like the she seems to have a plan to keep building the stories out, and that there are seeds of that from the beginning in book one. I like that the world keeps growing, and the characters and the relationships changing. I like the previous characters appear but don't take over in the following titles. I always have a good time reading these books and rooting for the main couples. I wish the main characters had a bit more variance in their backgrounds; I get that they grew up in a rough world, and that the world now is rougher still for them, but how is it every one of these people has pretty horrific violence and/or abuse in their childhood? It's starting to blur them all together for me, though the issue is less pronounced in their presents for the main action of the stories.
The real problem for me, and this may be less distracting for others, is that the series is filled with continuity errors that end up really pulling me out of the action, and in this book, they're glaring at the start, even if the overall plot and most of the punctuation works. Hopefully with the rights reversions Tyler can fix some of the earlier ones now, too, such as Caspar's mom going from Susan to Cara in different portions of book one, or the fact that Rebel and Luna were supposedly abused by the same person, but in Luna's book he's Adam and here he's Frank, unless I have misunderstood the story line and multiple members of Defiance were abusing local children freely.
I also spent more time than I want to admit flipping back and forth because in book four, the Chaos was supposedly 7 years ago, but only a couple years have passed since book one, as I understand it, and there the Chaos is said to have been almost two years ago. This also causes age errors, even if the seven years number makes some of the characters make more sense-- Declan was supposedly kidnapped at 16, but 7 years later the story says he's 21 (and clearly stated as 20 in book 3). Ditto Rebel-- he's 17 in the intro, and the references just never come together. This actually caused me a few minutes of major issues with this one, because I started Temperance and got no further than chapter one before I quit reading it to go and check my memory.The math on Kammy-Keller-Declan between books 3 and 4 confused me, as well, but I decided there's just more to that story I don't know and appeased myself that way. I even think that Mathias and Bishop trade coloring descriptions over which is the blonde and which one is darker, which briefly made them difficult to tell apart for me in places.
I admit this may seem nitpicky, but I get caught in details like this and end up having to go double check my memory instead of enjoying the story, so I couldn't leave it out and feel like I'd given an honest review. It is just how my mind works; those sorts of problems send me straight out of the story and into research mode. All in all, though, I enjoyed this addition to the series. The ending felt a bit abrupt and unfinished for me under the circumstances, but I assume too that's because further details on what happens to Rebel and Declan after the concluding scene would include spoilers for book 5.
