This has been my favorite 13th Doctor novel yet! While I was hesitant about the return of the Nimon, this proves to be a globetrotting adventure that feels authentic to the era while also developing these characters further than what we see on screen. Yaz, Ryan, and Graham all shine quite a bit in this book. Graham especially we spend a lot of time with, and we see him in his lowest points and his highest, given Ryan’s life is at  stake for the second half of the book. There are a few Thasmin moments between those two characters, which is very cute. The two antagonists are very hatable and easy to root against, though I’m unsure how I feel about their redemption at the end. The whole book just feels like this huge finale to the season 11B era of the show that we never got.
