This book was a lot of slow slow slow A MILLION THINGS AT ONCE slow slow slow OMG EVERYTHING IS HAPPENING slow slow slow BIG ENDING slow...

I really liked the setting and the story once I got into it (which took about 3 times as long as most books) but what got me was how little Ethan asked about the Caster world. Everything he learned after initially finding out that Lena was a Caster was stuff that just came up. I would have wanted to know every little detail. And I don't feel like we ever figured out exactly what Macon was. Because if he wasn't a Caster then how could he have been Lena's actual uncle? And if he wasn't her uncle why was he so involved?
I know there are many other questions that will likely get answered in the next books but I feel like those were supposed to be in this book. I'll need a break before book 2, but at least I can watch the movie now!
