“I couldn’t stop reading! Absolutely a triumph!”Freida McFadden

From the internationally bestselling author of Strange Sally Diamond comes a twisted and brilliantly observed new novel about two sisters and the lies that shape their lives.

If my sister hadn’t been beautiful, none of it would have happened.

Ruby Cooper and her sister, Erin, live an idyllic life in their close-knit church community in Boston. But when Ruby is sixteen, she is involved in an incident that causes her family’s world to implode.

Across decades, the fallout leaves a wake of destruction behind Ruby in Dublin and Erin in Boston.

Not that Ruby wants to think about the past.

But it can’t stay a secret forever.

The Queen of the Opening Line has done it again!

This is a perfect example of how to nail the psychological thriller, keep the reader utterly gripped and throw in several WTF and OMG moments that literally left me open mouthed with shock.

As a huge fan of Liz Nugent and having read all her books, I was delighted to get an early ARC copy of The Truth About Ruby Cooper. I was so excited I didn’t even read the blurb, so went in completely oblivious to what this story was about and if you need further proof of how much I loved it, I didn’t put it down and devoured it in a day, only stopping halfway to message Liz to say WOW.

I’m not going to spoil anything for you, but I will say it’s about a family, a shocking and awful incident and the cataclysmic and devastating effects it has on everyone from that moment on.

It’s raw and beautiful, brutal and heartbreaking laying bare some of the truths about addiction, recovery and the effect our actions have on those we love.

I’ve read everything this author has written so I was excited to read a 30 page sampler and I enjoyed it. It’s got quite a heavy storyline but it is a page turner and written in the authors typical style. I’m excited and intrigued to read more.

I didn’t read the blurb, I didn’t read the author foreword letter to the reader. I went in blind.

Ruby and Erin are sisters. The Truth About Ruby Cooper tells the story of the incident that happened when they were teenagers and the impacts on those concerned through the decades and through generations.

This is a completely original thriller, I’ve never read this angle before.

This is a masterpiece from Liz Nugent. Serious subjects, deeply involving believable characters, tightly plotted and with plenty of hard hitting shocks along the way.

Definitely a book of the year. Read it as soon as you possibly can!

This has been skillfully masterminded and is something quite different. It makes for a harrowing read but is nevertheless a gripping and dramatic thriller. Nothing is what it it first seems. I thoroughly enjoyed it and can highly recommend it.

If you love your stories sharp and your characters properly wicked, Lucy Cooper’s world is an absolute ride!

Practically inhaled this. Lost sleep over it.

Absolutely… LOVED IT.

There a deviousness running throughout - in the plot, in Lucy and her choices, in the way everything slowly tightens around her - that reminded me so much of Skin Deep (one of my favourite books.)

Liz Nugent REALLY knows how to craft a character you’re horrified and obsessed by in equal measure!

Fair warning: the subject matter definitely veers into the dark, and Lucy herself is… let’s just say morally flexible.
But that’s exactly what makes both her and the story so gripping for me.

It’s twisted in all the best, most addictive ways, and once the plot really starts to unravel… gah!! I was glued. GLUUUUED. To every page.

I was so thrilled to get an early read of this book, because Liz is one of my favourite authors! I've read and loved all her books. THE TRUTH ABOUT RUBY COOPER is is a brilliant page-turner about family secrets, sibling rivalry, and sex as a weapon. It's another dark, twisted Liz Nugent winner. I loved it!
