Lawrence writes in the language of many London teenagers. If you abhor deliberate grammatical inaccuracies in your narration, this is not for you. I enjoyed it and found the voices fresh and true. Lawrence, of Italian and Trinidadian heritage, can always be relied on to reference good music, and I loved her nods to K-pop and Marvel movies. Silva’s character I found a little less convincing, and the motive for her disappearance doesn’t quite add up.
