What an ending! Such a perfect finale to this great series... I really loved it!
The story is, as always, really well written, with a perfect pace. It's thrilling, emotional and very, very gripping. The main characters, Riza and Casey, are not only interesting, they feel real. Their motivations and emotions are easy to understand so you can't help it: you feel their fear, their pain, their confusion and hopelessness, but also their rage, their defiance and their need to stop the Brotherhood, forever.
The structure worked really well for me because it allows us to get to know the characters and sympathize with them, so pretty soon we are really invested in their fate.
And although I hate that this is the last book, is such a satisfactory ending that I can't get mad. And I'll live in the hope that the author won't make us wait too much for a new story in a new series :P
Oh, and Caroline McLaughlin's narration is simply wonderful ♥
