The book starts off with psychological thriller vibes then descends into a sort of dystopian science fiction. It's a debut which seems to be dividing opinion. I neither loved nor hated it. The audiobook narration by Helen Keeley is first class and elevates the material. Keeley skilfully assigns different voices and quirks to each character, helping to distinguish them and bringing Louise Mumford's creations to life. My favourite of which was undoubtedly Thea's Mum Vivian, with her Menopausal Army of women warriors, vagina scarf and key trick to fend off potential offenders. My biggest takeaway is that I will never complain about insomnia, ever again, for fear of being spirited away to a giant testicle in the middle of nowhere.
