I was given this book as a birthday present when I was 10 and wasn't sure if I would like it. Turns out, it was one of my favourite books and I loved the story. The story has adventure, suspense, mystery, science fiction, and romance all together. Even if you or your kid isn't into space, it is really interesting and I learned some new facts about science and space from this book. I would encourage you to take out this book and give it a try. The author, Stuart Gibbs, is a fantastic writer and has other series like FunJungle and Spy School that are super interesting, too. I highly recommend reading this book and for some reason can't give it stars but it would deserve 6 out of 5!
