I really loved the first book, and this one followed pretty closely. It seemed a little slow at first- many of the trials felt too similar to the first book and since we already knew the point (the Never Plan), it felt unnecessary to keep taking us through more of them. Adding the numbers later did shake it up a little bit, but I felt like I was reading another iteration of the prison guard experiment. The last 25% of the book was insane and I literally could not figure out how it could end. I did love Seb and Finn’s love story. They are adorable and you can’t NOT root for them. The number’s trauma challenges and the animal “trials” were all a little much for me and really made me so upset. Also, I didn’t like the absence of the real villains within this book, and having most of the story led by two new characters who we didn’t even really get closure about. Nevertheless, I think this says a lot of important things about mental health and being ourselves, and what it means to be happy.
