A nice third book in the story with Spensa yet again at the forefront. I know there have been complaints about the other characters largely being missing in lieu of her, but I don't mind this as I enjoy how well her character has been developed. I also greatly enjoyed M. Bot's development and the further questions presented on AI ethics. There are also some great new characters introduced in this book, so suffice to say I really enjoy the characters overall.

The Sci-Fi elements, well, while I thought the delver storyline was well written, it did feel a bit on the simplistic side to me. I've always preferred harder Sci-Fi though so your mileage may vary.
