Power of Six Book Review

Hi Guys,
This week I'm doing a review on The Power of Six by Pittacus Lore. This is the sequel to the bestselling book I am Number Four. This book switches perspective between Four and Seven. Seven is an orphan girl living in a convent. Four is still on the run from the FBI as well as Mogadorians. Here is the synopsis from the front flap of the book:

I've seen him on the news. Followed the stories about what happened in Ohio. John Smith, out there, on the run. To the world, he's a mystery. But to me . . . he's one of us.
Nine of us came here, but sometimes I wonder if time has changed us—if we all still believe in our mission. How can I know? There are six of us left. We're hiding, blending in, avoiding contact with one another . . . but our Legacies are developing, and soon we'll be equipped to fight. Is John Number Four, and is his appearance the sign I've been waiting for? And what about Number Five and Six? Could one of them be the raven-haired girl with the stormy eyes from my dreams? The girl with powers that are beyond anything I could ever imagine? The girl who may be strong enough to bring the six of us together?
They caught Number One in Malaysia.
Number Two in England.
And Number Three in Kenya.
They tried to catch Number Four in Ohio—and failed.
I am Number Seven. One of six still alive.
And I'm ready to fight.

My first reaction to this book was good, because I'd already read, and loved, I am Number Four. Not to mention that the cover of this book is amazing. I thought this book was decent, it seemed rushed to me. The only things that kept me reading this book were the characters and the plot. I liked Number Seven, I thought she was innocent and I liked how she looked out for others. I also liked Number four, Number nine, Number ten, Number six, Sam, and... you guys might not want to hear this... Sarah. I know, I know... what she did to Four was wrong, but I think there had to be something that happened that made her do that to him. I still think she's a good person. I like Sam and Six's chemistry throughout the book, and I liked how four and nine were not afraid to kick butt towards the end. Number ten amazed me from the moment I found out who she was. I didn't like Number Seven's cepan... she was a total... never-mind that... I did start to like her towards the end, as for the other nuns... i didn't like them. I gave this book 3/5 stars because the only things I liked about it were the characters and the plot. The dialogue was horrible... and there were other reasons I didn't like this book, but I don't want to go through them. I did like the book though. I think people should read it, there is always at least one book in a series that is horrible, and this is that book. I hope the next one will be really good. :D
