United As One (Lorien Legacies #7) by Pittacus Lore
Publisher: Michael Joseph
Goodreads Summary: 
The epic conclusion to the New York Times bestselling I Am Number Four series!

The Mogadorian invasion has come to Earth, and they have all but won the battle for our planet. Their warships loom over our most populous cities—like New York City, Tokyo, Moscow, Beijing, and New Delhi—and no army will risk making a move against them. The Garde are all that stand in their way . . . but they are no longer alone in this fight. Human teens from across the globe, like John Smith’s best friend, Sam Goode, have begun to develop Legacies of their own.

The Garde have always known there is power in numbers. If they can find these new allies and join forces with them, they just might be able to win this war. The time has come for the Garde to make their final stand.
Rating: 4 Stars
Action packed? Yes. Exciting? Definitely. Addicting? Not really. While most of the time I enjoyed reading United As One, there were a lot of moments during which I got bored, and struggled to keep reading. The plot and storyline are as good as the previous books, but the execution is terrible in some places.

My main issue with this book is that one minute it's action, the next it's your average day. I don't think it flows like a story should, but when it came time for a battle, they were definitely well written, planned out and included plot twists.

It took me awhile to recall the characters as it's been quite a while since I read the rest of the series in a rapid succession. I expected United As One to be as good as its predecessors, but unfortunately this one disappointed me.

A weak end point for the series, but I'm not going to forget how good the last six books were. In this book just as many characters died, but the ending is rushed and quite a few were brought back to life, as if Pittacus Lore was trying to create a HEA. As for the last chapter 'one year later', I didn't like what happened in the chapter.
