Listened to the audiobook, narrated by Finty Williams, over the course of a couple of long summer road trips.

An interesting and engaging book! It applies the setting of a women's prison in England to a meditation on death, injustice, and our obligations to ourselves and each other. It has a strong supernatural element, but most of the characters and plot points are grounded in the 'real world'.

The only thing criticism that I have is that the main character undergoes a very dramatic change of perspective at the beginning of the book. She starts out as an unfocused and disengaged woman with serious drug addictions. Her transformation to a highly-principled protagonist feels like it warrants a bit more interrogation that it received here.

Still, recommended, particularly for fans of Carey's other works.
