This is one of those books that I have no clue how to rate, except that it will be at least three stars or more. It had a lot of things going for it and a had a lot of aspects that I personally have been missing in YA fiction lately. Rachel Bach writes with maturity that is pleasing to the brain. Buuut, there were things that I also didn't like. 
 First of all, to all you crazy blokes who say things like, "women can't write science fiction" or, "girls and women don't read science fiction. It's a man's genre." Shut the pie hole! Cause this is one amazing science fiction novel written by a woman whose writing I'm coming to admire a lot. Also, we read science fiction. 
 We'll start with the amazing stuff that Ms. Bach does in this book: 
 1. This book is freaking exciting! There's almost non-stop action, mystery, and danger. I was constantly worried for the lives of the characters aboard the Fool and was hoping that they would all get out okay. Well, most of them... The action scenes were written magnificently and it was like watching a movie unfolding in my mind. I could so clearly picture Devi in Lady Gray, shooting aliens with Sasha and Mia- not to mention those crazy camera-eyes and flips that her motored armour helps her with. 
 2. There are ships in space. Spaceships, or if you'd rather, AIRSHIPS. I LOVE AIRSHIPS AS ALL THE WORLD KNOWS BY NOW. And there were aliens. Lots of really, really neat aliens. Not to mention all the cool science fiction aspects of the technology and weapons. While obviously these things would never happen today or in the next few years, it wasn't too hard to suspend my disbelief and that made this book very satisfying. BUT LET ME REPEAT, THIS IS ABOUT A CRAZY, KICK-BUTT HEROINE FIGHTING ALIENS IN SPACE. Awesome! 
 3. 
 4. Have I already mentioned the fact that it's in space? And that the setting seemed really neat? No? Consider it mentioned now. Believe me when I say that the Space aspect made this book. 
 Things I did not like: 
 1. Most of the main characters besides Devi. I thought that Caldswell, Mabel, and Nova could have been much more developed and made more interesting. 
 2.Mainly, the love interest, Rupert. He had very little uniqueness or personality about him. (view spoiler)[Sure he was actually a really dangerous parasite alien living inside a host, but how does that make him different from all the 'dangerous non-human romantic interests' in so many books? It doesn't. (hide spoiler)] There was very little in him that justifies Devi actually loving him and the amount of time she knew him didn't convince me that this was actually any different than her other lovers she talks about. There is nothing about Rupert that explained Devi's head over heels in love-ness for him. It was irritating. 
 And even worse, there was very little to explain his obsession with her! Also, the amount of times he treated her, helped her, protected her, or was described as having a look that was rather possessive was so irritating. I would have liked to see a little less of him attempting to protect her and a little more actual personality given to him. 
 So the love story obviously irritated me, but good news, there was more to this story than the romance, so even if that was the case, I still like it lots! I will definitely be reading the second book as soon as possible, especially after the ending that Bach puts the reader through. So intense! 
 But anyway, this book was fantastic, enjoyable, and an edge of the seat adventure that will keep any science fiction lover reading through the night! Four stars!
