The plot never quite reached the heights it aspired to, but it was fun enough with side characters dying some delightfully gruesome deaths. The best part of this book was by far the relationships between the Doctor and her companions - I have found it in my heart to forgive Stephen Cole after he wrote (and I very much did not enjoy) The Ancestor Cell.

This is certainly not a must-read, but as a series 11 era adventure, it’s one of the better ones and does a really good job fleshing out different key aspects for each companion, some better than others. Ryan is really great in this, whereas Yaz follows the Doctor around asking questions like usual. The Doctor herself is great, and I love the pacifist message.
