About the book

From the #1 internationally bestselling author of The Murder Rule comes an emotional novel of suspense about two families pitted against each other — one seeking justice in the disappearance of their daughter, the other desperate to clear their son’s name.

Nina and Simon are the perfect couple. Young, fun and deeply in love. Until they leave for a weekend at his family’s cabin in Vermont, and only Simon comes home.

WHAT HAPPENED TO NINA?

Nobody knows. Simon’s explanation about what happened in their last hours together doesn’t add up. Nina’s parents push the police for answers, and Simon’s parents rush to protect him. They hire expensive lawyers and a PR firm that quickly ramps up a vicious, nothing-is-off limits media campaign.

HOW FAR WILL HIS FAMILY GO TO KEEP HIM SAFE?

Soon, facts are lost in a swirl of accusation and counter-accusation. Everyone chooses a side, and the story goes viral, fuelled by armchair investigators and wild conspiracy theories and illustrated with pretty pictures taken from Nina’s social media accounts. Journalists descend on their small Vermont town, followed by a few obsessive ‘fans.’

HOW FAR WILL HER FAMILY GO TO GET TO THE TRUTH?

Nina’s family is under siege, but they never lose sight of the only thing that really matters – finding their daughter. Out-gunned by Simon’s wealthy, powerful family, Nina’s parents recognize that if playing by the rules won’t get them anywhere, it’s time to break them.

Author’s Note

Author’s Note

This book was always about the parents for me. I knew the structure was going to be a bit unconventional, in that you find out answers to key questions early on, but I felt fairly confident that readers wouldn’t be thrown by that. I think readers of crime fiction are very familiar with traditional narrative, and they like it when you mix things up, as long as the story is powerful. Despite the title, the book isn’t really about What Happened to Nina, it’s about everything that happens after her disappearance. About two families who go to war because they are each willing to do whatever it takes to protect their child.

Awards & critical praise

‘Addictive. Propulsive. Less page-turning than page-devouring. The story builds like a nuclear mushroom cloud. Dervla McTiernan is a thriller master.’

Trent Dalton

‘Her best yet. Completely riveting … I had at least three gasp-out-loud moments. And that ending! Everyone’s going to be talking about that ending.’

Sally Hepworth
bestselling author of The Soulmate

‘McTiernan has crafted an engrossing and shocking story inspired by tragically familiar events. The power and influence of social media makes for a compelling secondary story here and shows how quickly misinformation can spread. Fans will have a tough time putting it down.’

Booklist

‘Had me tearing through the pages, even after the ‘who’ of the mystery had been revealed. A great read for fans of Hayley Scrivenor’s Dirt Town and Emily Ruskovich’s Idaho.’

Books+Publishing

‘McTiernan turns the traditional thriller on its head … truly haunting.’

Kirkus starred review

‘A propulsive and satisfying mystery that tackles head-on themes of wealth, power, domestic violence, and the stories we tell ourselves to justify our worst actions. This is Dervla McTiernan at her finest.’

Tracey Lien
Internationally bestselling author of All That’s Left Unsaid

‘Gripping … A smart and unpredictable portrait of how the boundaries between tragedy and entertainment get blurred. It’s a disturbing treat for thriller fans.’

Publishers Weekly

‘One of the best thrillers I have ever read. It is an unforgettable and deeply moving read that takes the concept
of how far would you go for your child and turns the volume up so high the dial breaks. Dervla McTiernan is a wickedly gifted writer.’

Don Winslow
#1 Internationally bestselling author of The Cartel and City on Fire

‘A stunning masterpiece. Haunting, emotional, fiercely intelligent and absolutely diabolical. I felt like I was living inside this story.’
