OK... OK... OK... I'm going to need a minute for all the adrenaline to wear off. This book was basically all just action, upon action, upon action. I'm not saying it's a bad thing. 
 These last 3 books (Revenge of Seven, Fate of Ten, & United as One) in the series are like one giant finale that is split up over 3 books. Fate of Ten is the is the action packed fudgey core of the cupcake. It's hard to review it because I still need to see the full picture that will be presented in United as One. This is just the events leading up to the real conclusion. However, they are some game changing, crazy, wonderful events! SHIT GOT REAL! AND THAT ENDING! I'm just going to admit it... I was totally ugly crying. 
 Everything I say will be super spoilery so I will just geek out below: 
 (view spoiler)[ 
 1. So there's new Guard all over the place. I'm not sure what this exactly means for the future. Yes, it's awesome that there are new Guard to help defend Earth and fight the Mogadorians. But what's going to happen after the invasion? (I assume they are going to win because no one would stand for an unhappy ending!) I think the world would turn into a kind of X-Men situation where the Guard are feared and persecuted for having abilities. :/ 
 2. Ella is a G. There was no way they were going to kill off a 12 year old girl! But man did she have it rough. When she said her body didn't work anymore and all she had was her mind, it got me in all the feels. 
 3. Look at John being all leader like! You go you Pittacus BAMF! Ximic for the win! 
 4. Argh Marina! NOOOOOOOOO! At least she's not dead... yet. :( 
 5. SARAH! NOOOOO! THAT'S HOW YOU ENDED THE BOOK!? WITH HER DYING BREATH WHILE SHE TELLS JOHN SHE LOVES HIM ONE LAST TIME OVER THE PHONE!? I'M SURE SHE WON'T REALLY DIE AND SOMEHOW JOHN WILL SAVE HER IN UNITED AS ONE, BUT STILL. I WAS UGLY CRYING! 
 6. Maybe 5 will help somehow and maybe reconcile a bit with the others. I don't think they are ever going to be friends but maybe they will at least come to a peaceful understanding. 
 7. Side note: I know it's weird because Ella is so young but I'm shipping her and 9. Like when she's older obviously! There's at most a 6 year age difference which really won't mean much once she's grown up.

 Ok... I'm done geeking out. Can't wait for United as One to come out in a few days!
