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
Andrea Mara's tight plotting and convincing characterisation make her books both compelling and intriguing.
Liz Nugent, author of LYING IN WAIT
With a genuinely terrifying opening, fans of Big Little Lies will enjoy this slice of twisty domestic noir with a distinct south Dublin flavour.
Sinead 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 horrified 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
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
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
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. This book will fly!
Sarah Pearse, bestselling author of THE SANATORIUM
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!

All my greatest fears on the page and yet I couldn't stop reading. Congratulations, Andrea Mara, you evil genius.
Sarah Breen, co-author of OH MY GOD, WHAT A COMPLETE AISLING
Someone has taken Marissa's child; the fun in this fiendishly twisting narrative is trying to work out who that might be.
Irish Independent
This is a book which would probably reward a second reading, perhaps a few months later, when the details have faded a little from memory. It's really that good.
