Marissa Irvine arrives at 14 Tudor Grove, expecting to pick up her young son Milo from his first playdate with a boy at his new school. But the woman who answers the door isn’t a mother she recognises. She isn’t the nanny. She doesn’t have Milo. And so begins every parent’s worst nightmare.


As news of the disappearance filters through the quiet Dublin suburb and an unexpected suspect is named, whispers start to spread about the women most closely connected to the shocking event. Because only one of them may have taken Milo – but they could all be blamed . . .

All Her Fault – author reviews:

Wow, All Her Fault gripped from the first page and didn’t let up! It played on my worst fears and kept upping the stakes…great plotting, I didn’t predict any of the twists and turns! Superb characters that were brilliantly crafted. Congrats . . . This book will fly! – Sarah Pearse, author of THE SANATORIUM

Wow! Loved it. The pace is breakneck. A book where no one is who you think they are. And just when you think you have it all figured out you are thrown another curveball. Highly recommended. I flew through it. All Her Fault will be a huge bestseller. ― Patricia Gibney, author of THE LOST CHILD

Immediately compelling, All Her Fault explores every mother’s worst nightmare and delivers deftly original twists. ― Phoebe Morgan, author of THE BABYSITTER

With a genuinely terrifying opening, fans of Big Little Lies will enjoy this slice of twisty domestic noir with a distinct south Dublin flavour. ― Sinéad Crowley, author of ONE BAD TURN

All Her Fault drops you straight into a nightmare scenario that plays on some of our worst fears. The delicious equivalent of a binge-watch, I powered through this book in one sitting. Think Big Little Lies meets The Undoing – I had a blast accusing everyone of everything, as each chapter introduced a new twist or revelation to undo my prior conviction. A fantastic, immersive read, proving that people behaving badly really do make for the best company! ― Jacqueline Bublitz, author of BEFORE YOU KNEW MY NAME

A wonderfully twisty nightmare of a domestic thriller. ― Emma Curtis, author of KEEP HER QUIET

One of Mara’s myriad talents is identifying those subterranean paranoias of modern life – the vulnerability of an online presence, the trust we place in strangers – and masterfully worrying at these fears to keep us hooked and horrifed in equal measure all the way to the last page. All Her Fault simmers with unbearable anxiety before the gut punch of its charged and riveting climax. You cannot look away. ― Sophie White, author of UNFILTERED

Gripping and twisty. ― Andrea Carter, author of the Inishowen series 

From its heart-stopping opening through to the twist on the final page, I raced through All Her Fault. It says a lot about Andrea Mara’s fantastic plotting that I never guessed whodunnit – and I more or less suspected everyone. ― Nicola Rayner, author of THE GIRL BEFORE YOU and YOU AND ME

I couldn’t put down All Her Fault, so many wicked, wicked twists! Utterly gripping, so believable and just the most perfect ending. Superb! ― Sam Blake, author of THE DARK ROOM

It was gripping and emotional and I couldn’t put it down. The twist was intricately woven into the storyline, but so cleverly done that I didn’t see it coming at all. I loved the relationship between the women, and the wonderful portrayal of female friendship developing even in the darkest of circumstances. ― Eleanor Ray, author of EVERYTHING IS BEAUTIFUL

A thought-provoking rollercoaster of a read with a shocking but satisfying twist – highly recommended! ― Roz Watkins, author of CUT TO THE BONE

All Her Fault is a fantastic read. Gripping and real, with a whole host of flawed characters, it explores motherhood, relationships and friendship in a twisted unravelling of every parent’s worst nightmare. ― Lauren North, author of THE PERFECT BETRAYAL

A dark and twisted thriller which will make most parents triple check their security settings! This is another cracking read from a writer who is at the top of her game and wow… that twist floored me! ― Claire Allan, author of HER NAME WAS ROSE

A great page-turning thriller with fantastic twists. Loved it. – Sinéad Moriarty, author of ABOUT US
