This book is not a who done it. We know. It instead explores the effect of young Nina's murder on her family and on the family of her boyfriend, Simon. It explores current issues like violence against women, wealth and entitlement, social media and trolling, grief and revenge, and powerlessness in the face of hostile misinformation. No one emerges undamaged. You will feel angry and wish that justice could have come more quickly. You may even wonder how you might act in this scenario. I read it in one day, couldn't put it down.
