Aggressively good. Saskia Maarleveld has incredible taste in books. If she's narrating it, i know it will be a banger. And she's amazing at what she does!
I really, really enjoyed this story. The plot twists made complete sense and I felt proud of myself whenever I managed to see one coming, the characters are lovable, (I want to give all our protagonists a hug) and the descriptions of sensations were vivid and visceral. I loved every moment. 
It was also a stunning portrayal of how people deal with trauma, especially trauma inflicted by one's primary caregivers. Excellent work!

My one critique would be that they struggled a bit with writing the 4-person conversation between Ester, Johanna, Nicholas and Collins where the 're trying to decide what to do with the wards. It felt forced and repetitive, and constantly reminded me of the fact that this is a story written by a person, and not just me being a fly on the wall for a real life conversation. I didn't notice this with any other conversation.
