This is an immense debut. The chapters merge the interpersonal relationships of a mother and daughter as the mother is dying from cancer. But there is an interloping voice, disembodied and impish, that slowly takes over the novel. In the audiobook, this is performed by Tamsin Grieg and she is absolutely incredible at interpreting this witchy mysterious vicious unknown that could be the cancer but could be something else. 

I found the changes of pace a bit inconsistent and was most captured by one part of the book. Nonetheless, it is epic, clever, messy, and bitter. Clearly, an author to watch.
