Confession time...I almost didn't read this book, the third and final in the series. I know, I know, why read the first two and not the last. Well I have to admit I just wasn't crazy about the second book and it kind of turned me off. It was okay, but not what I had wanted/expected. With that said, when I was granted an early copy of Into the Still Blue, I knew I needed to read it so I did. Another confession...it was my absolute favorite of the three. So I guess there is that. 
 Into the a Still Blue literally picks up where Through the Ever Night left off. Cinder is gone with Roar out after him. Perry and Aria have just gotten back from the now extinct pod with a new group of dwellers and a whole lot of problems. Faced with the fact that the Aether is quickly folding in on them Perry has to make a decision for the Tides and he has to do it fast. Unfortunately when Roar returns back to the Tides he doesn't seem too pleased with Perry or willing to help him. But through him they learn that Hess and Sable have joined forces and all bets are off. Instead of just worrying about the Aether and the Still Blue Perry has another force to deal with and it could be deadlier than anything else...Sable's thirst for power and control of everything. 
 First things first, Into the Still Blue was action packed. Everywhere you turned there was something going on that left you breathless and wondering how the characters were going to get out of the given situation. It definitely worked to keeping me on my toes and wanting to read more. And I think was a huge part of the reason I didn't like Through the Ever Night as much as it seemed boring. But Into the Still Blue was anything but boring. Actually it was downright enjoyable. Was some of it unbelievable and staged, definitely. But it worked for the story so I didn't hate it. All the twists and turns seemed unexpected and expected at the same time and it all worked well. I do with there was more to the Sable story, but I won't get into that as I don't want to give anything away. But even with all the action, what I liked the most about the story was the characters. 
 From book one we got to really know Aria, Perry and Roar. We got to hear their thoughts and feel their feels and live their lives. We saw where they started and where they ended and I have to say the transformation was remarkable. Rossi made them grow up right before our eyes. These three people were very lost in Under the Never Sky. They formed a bond but didn't have a place. But as life moved on and circumstances changed each one of them adapted and become strong and independent characters that I know I personally appreciated. I will say I thought Roar being mad at Perry the way he was was a little strange, but I got the idea behind it and it did logically make sense. That aside it was remarkable to see the bond just strengthen between these friends, and in the case of Aria and Perry, lovers. They relied on one another and we relied on them and Rossi delivered. 
 Without giving anything away, Into the Still Blue will take your breath away and having you on the end of your seat while smiling and laughing and maybe even tearing up. It was the perfect way to end a great series and I'm thankful I didn't skip this book. It washed away the icky feeling from book two and made me love all of them again. Well done Ms. Rossi, well done.
