This book was enjoyable! It was an interesting follow up to the New John Connor Chronicles trio, but going into the book I was a still confused as I didn't remember half of the people that they kept bringing back from Evil Hour. One good thing was that I felt that this book had one of the better depictions of Sarah. Though overall, I would definitely agree with other reviews with how this book was a little wordy and a bit too much focused on the actual science of everything. Though at the same time, I felt that things weren't explained enough, like how the whole ending portion didn't seem that clear with the time jump that John experienced or what actually happened to the TX-A. I feel like it could have just had a more definite ending, it seemed fairly rushed and while everything did get "resolved" it also felt like it didn't and I was left wanting more. Overall, it was a really enjoyable book. I liked how he did all of the characters and did fit in nicely into that universe.
