Where the last two books lacked momentum and action, this one has all that. The first two books didn't accumulate a lot of stars, 3 and 3,5, but this book on the other hand, has taken a major jump up the scale.
You know when you start reading a book, and you get that feeling where you just have to read a little longer before you put it down? The last two books (again) didn't have that. To put it short: they were slow. Very slow.
Dev is still evolving, and all the questions left from "Make You" still stands. Will Base join the hunters? When will "the Big Bad" turn up? Who will live, and who will die?
This is a well executed book, my only regret being that the end felt a little rushed. That said: if you can get through the first two books, this one is well worth your time. I loved the Ava Delaney series, and in this book the author presents some of the same writing skills as she did back then (I haven't gotten aroung to read "Lost souls" yet, but I will!).
Right now it's actually sad to see the story ends. Now, when it finally turned out to be so well written! Anyways, three books is enough for the storyline, so I guess it's a good thing she didn't try to squeeze out another one, just to keep it going. :)
