Andrea Mara is a crime novelist from Dublin, Ireland, where she lives with her husband and three young children.

Her newest book, All Her Fault, will be published by Transworld | Penguin Random House in July 2021.

Her first book, The Other Side of the Wall, was shortlisted for the Kate O’Brien Award 2018 and was recently an Amazon number one bestseller in Irish Crime.

Her second book, One Click, was shortlisted for Irish Crime Novel of the Year at the 2018 An Post Irish Book Awards, and a recent number one on Amazon in Irish Crime and Northern Irish Crime.

Her third novel, The Sleeper Lies, published in February 2020, was an Irish Times Top Ten Bestseller.

Andrea also runs multi-award-winning parent and lifestyle blog,


That’s the official bio – here’s the background:

In a departure from blogging and freelance writing, in 2016 I turned to murder, mystery and suspense, and my first novel The Other Side of the Wall was published by Poolbeg Press on June 6th 2017.

The Other Side of the Wall Andrea Mara Office Mum


The book was partly inspired by the very regular night-time wakings of my youngest child, though I’m glad to say – unlike my main character – I never saw a body in the pond next door.

It’s about normal houses on normal roads and asks the question – how well do we really know our neighbours?

One Click

My second book, One Click, was published on May 1st 2018, again by Poolbeg Press. It’s about a woman who takes a photo of a stranger on a beach then posts it online, with no idea of the unintended consequences to follow. Again it was inspired by a real life situation – in real life, I didn’t take the photo.

The Sleeper Lies

My third book is a mystery thriller set during the big snow of March 2018, about a woman who lives in the middle of nowhere. She looks out one freezing morning and sees a trail of footprints across her snow-covered garden, right up to her bedroom window, where they’re deeper, as though someone stood for some time looking in at her while she was asleep.

Jump to The Sleeper Lies for the full blurb – publication date was February 2020.

All Her Fault 

In 2020, I signed a new two-book deal with Transworld, part of Penguin Random House. The first of those two books, All Her Fault, will be published in June 2021. It’s a story about a woman who goes to collect her child from a playdate, only the person who answers the door has never heard of her son. Cover coming soon!
