I really enjoyed this book! It pulled me in right from the beginning, and it never slowed down. There's something happening in every chapter, and the book continues to move at a consistent pace so there's always something new to learn and explore, and it never gets boring. The one thing I wish there was more of was depth and detail about the characters and the world. I feel like I only got a vague glimpse into who these people are and what their world looks like, and some of the things they went through each day. But I did enjoy the variety of characters present, their personalities and beliefs, and the different viewpoints about the Number system. Overall, it was a solid read and I look forward to picking up the next book!
