The playground
(Book)

When their children join the same tutoring circle, the lives of three London couples collide. The results: illicit relationships, shocking violence, and unimaginable fallout. There's Eve, a bougie earth mother with a well-stocked trust fund; Melissa, a successful interior designer whose casually cruel banker husband is careful not to leave visible bruises; and Grace, a young Zimbabwean immigrant living in a high-rise housing project, doing far more for her family than she should have to. The couples become so distracted and self-absorbed that no one sees the five children at their secret games-- or realize how much their family dynamics are changing until tragedy strikes.
