 Spoiler Free Review: 
 I don't usually read many middle grade sci-fi books, but this story in particular was a great one. It was a lovely read and I loved the characters, technology, and the adventure. The beginning started off as a set up to the world and was a bit difficult to get into. After Eva's underground Sanctuary is destroyed, things start to pick up. I was glad about the setup at the beginning because it cleared up a few questions I had about Eva's life. The "outside world" was rich in detail and you could tell that the author spent a lot of effort on the world. One of my favorite things were the full page illustrations at the beginning of every chapter. It beautifully depicts the story well and makes it easier to actually imagine a complicated world. 
 In addition to the world, the technology was also very fascinating to read about. It was obviously very advanced than the kind we have today. Eva had an Omnipod on her wrist,an artificial intelligence program that helps her out whenever she needs it. Though it could be annoying at times, it reminded me of an advanced Siri. The Omnipod played a large role in Eva's survival. 
 I also really liked a lot of the creatures that were introduced. They were unique and the author did a great job creating all of them. I loved the water bear behemoth, Otto. He reminded me of Appa from Avatar: The Last Airbender. He was loyal to Eva till the very end. Rovender was also a very sweet character, especially towards the end. He is in a way, a fatherly figure to Eva and I thought their relationship was so sweet and adorable. There was also Muthr Robot, Eva's caretaker. In the beginning, I found Muthr to be rather annoying, she was holding Eva back from all of the things she wanted achieve. Honestly, I think my initial thoughts was annoyance because I'm a lot like Eva, stubborn and someone who always wants to get their way. My thoughts on Muthr did eventually change. I realized regardless of whether she is a robot or not, Muthr was Eva's true mother in the end. I will say I was very put down and saddened by the ending of Muthr. I really wanted a little more from her. 
 My one minor issue was I had a hard time picturing the world. I'm not sure if this is only me, but without the pictures, I was very lost on how the world looked like. I'm not sure if this is only me, but I think it's because I relied on the pictures a little too much to imagine the world. Either way, Mr. Diterlizzi created a fascinating world. 
 The whole time I was reading this book, I was thinking about how great of an animated movie it would be. The full page illustrations go so well with the story, and I think an animated film would be very engaging and entertaining, especially for a younger audience. 
 Overall, I thought this was a fantastic start to a series and I'm really looking forward to the next few books. 
 Rating: 4.5/5
