All the missing girls - Megan Miranda

It's been ten years since Nicolette Farrell left her rural hometown after her best friend, Corinne, disappeared without trace. Then a letter from her father arrives - 'I need to talk to you. That girl. I saw that girl.' Has her father's dementia worsened, or has he really seen Corinne? Returning home, Nicolette must finally face what happened on that terrible night all those years ago.
Then, another young woman goes missing, almost to the day of the anniversary of when Corinne vanished. And like ten years ago, the whole town is a suspect.
Told backwards - Day 15 to Day 1 - Nicolette works to unravel the truth, revealing shocking secrets about her friends, her family, and what really happened to Corinne.
Like nothing you've ever read before, All the Missing Girls is a brilliantly plotted debut thriller that will leave you breathless.
