You can feel the suffocating heat rise off the page in this book (set in the UK = no air conditioning 🤷🏼♀️). A child goes missing, her teacher, Rachel, has a good idea where she has gone. This is a woman who seems to be struggling with her life: an absent husband, full of insecurities about her looks and her age, loss of control of her daughter. I really liked this, and if you like the unlikeable protagonist trope, you will too.
