The very best non romance scifi book I have ever read I loved everything about it from the world to all of the characters. I loved all of the characters though the one I loved best was Spensa an headstrong doesn't take anything from anyone character who would do anything to prove herself more than what it is believed her Father was. She is also very flawed and very human and so very relatable I really loved her character so very much. I really loved the plot it started with something from the past where everything went wrong and Spensa wanting to be able to prove herself not a coward and to prove the same of her Father.The moves on to her getting into flight school meeting some people not liking some finding out the spaceship she found was sentient and learning many things from that. The story moves on characters die there are more things found out and by the end the truth is known. So overall I loved this book will be reading the sequel soon.
