Overall I thought this was a really interesting book! It wasn't something that I would normally pick up myself, but I'm glad I read it! I don't want to spoil the ending, but I have to say that I was very pleased with how it ended. The reason I gave it four stars instead of five stars is because I thought the writing could be a little bit better. But I still enjoyed it regardless! The world building was great and I really enjoyed the characters. It was great getting to watch the characters learn and grow throughout the book. I also thought the concept was interesting. I would love to keep reading other books from this author, hopefully more will come out soon. I definitely recommend this book to anyone interested in reading it!
