Reviews

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*

A heart-stopping tale . . . Mara's stunningly original plot has its roots in the powerful emotions aroused by motherhood, leading to heartbreak and murder.
*Sunday Times, Crime Book of the Month*

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*
