Publisher's Summary

The seventh and final book in the number-one New York Times best-selling I Am Number Four series! With United as One, this action-packed series comes to a surprising, breathtaking, and utterly satisfying conclusion.

The Garde didn't start this war, but they'll do whatever it takes to end it once and for all....

The Mogadorians have invaded Earth. Their warships loom over our most populated cities, and no country will risk taking them head-on. The Garde are all that stand in the way, but they'll need an army of their own to win this fight.

They've teamed up with the US military, but it might not be enough. The Garde need reinforcements, and they've found them in the most unexpected place. Teenagers from across the globe, like John Smith's best friend, Sam, have developed abilities. So John and the others must get to them before the Mogs, because if they don't their enemies will use these gifted teens for their own sinister plan.

But after all the Mogadorians have taken from John - his home, his family, his friends, and the person he loves most - he might not want to put any more lives in danger. He's got nothing left to lose, and he's just discovered he has been given an incredible new Legacy. Now he can turn himself into the ultimate weapon. So will he risk his life to save the world, or will he realize that power in numbers will save us all?

So much promise!

For an entire series i was along for the ride. Epic battles book after book with Twists and turns. Such a great series. then came the final book. i listened and was sad you only got two voices, only two narrators, only two minds. For a book that called itself united as one I was sorely disappointed that it ended so haphazardly and everyone left went off on their own. The unity and family was missing in this book. They forgot what had made the other books great and almost ruined everything by turning it into a revenge and violence novel instead of being multi voiced and character driven. So sad, too bad, oh well. so unsatisfying. Now I have to find some fanfic writer who wrote a better ending to such an awesome series.

Meh

I'm a huge fan of the book series, however as the final book I felt it was a little lack luster. Even of this was not the finale this was definitely the least exciting book. However it does not ruin the series one bit. Fantastic series!!

Cry or smile.

I don't know whether the cry or smile but I have to say it was a good ending but like all books I wish there was a little bit more I don't know how I feel about the ending but I hope maybe one day that'll be more books to build on top of this one

Series Finished... Wanted a little more

This book was pretty good. I wish it had a little more in the after what happened. It was interesting, but I feel the writer wanted to just finish the series and get the book done. I still recommend reading this book it lets you finally complete the series

The climatic ending was AWESOME

Overall the story wrapped up the series nicely. I did however, feel that the first half of the book really dragged on. More character development, more legacy lessons... And there seemed to be more bad language in this book than in any of the others. I didn't care for the voices either. The voice of John was too old. It worked when he did Nine's voice, but for John he was way to old and gravely, and his "girl voice" was just weird. The voice of the Mogs and Setrikus was fine. The voice of Six was very flat and monotone, though when the actress did other female voices she was better. Overall it was hard to listen to, with the voices and the cussing and the lonnnnggg first half. The climax however was AWESOME and redeemed a lot, leaving me glad I'd stuck it out.

Not the best narrator choice

Would you listen to United as One again? Why?

Probably not. While I've enjoyed the series, the narrator killed this book for me.

What didn’t you like about the narrators’s performance?

About 10 minutes into the book I almost stopped listening due to the male narrator. This is a book that is supposed to be from a teenage boy perspective, so why does he sound like a 60-year-old smoker. It only got worse with the voices used for all the other characters. I do think this narrator would be amazing in a spy novel or some older police detective role, but this was horrible. Even the female narrator sounded way too old for the character of Six. I did complete the book as I wanted to finish the series, however it's not one I would enjoy listening to again.

A series I will cherish for a long time.

You could say perhaps that I grew up with this story. I remember when I started reading, and compare it to now with a smile on my face.
The story is delightful, the only problem I had was poor character design, everyone's monologue seemed the same.
All the same, loved it.
