*THE NUMBER ONE BESTSELLER*

The deliciously dark new suspense novel from the international bestselling author of Strange Sally Diamond

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.

‘What a read! A brilliantly dark and tangled web that every reader will be completely ensnared by’ Graham Norton

Critic Reviews

Dark, fearless and compelling - in other words, classic Liz Nugent. Utterly distinctive and unique, this is another unforgettable work from an outstanding and brilliant crime writer.
I couldn't stop reading! Absolutely a triumph!
An absolute belter of a book ... Liz Nugent at her dark and twisty best (Louise Kennedy)
Absolutely gripping. Another utterly compelling, dark and unsettling piece of work that’s going to give me a book hangover for weeks.
What a read! A brilliantly dark and tangled web that every reader will be completely ensnared by. (Graham Norton)
Only Liz Nugent could have written this book ... an unflinching, darkly funny, sometimes disconcerting and always gripping story (Sinéad Crowley)
Liz Nugent is fearless in the places she will go to uncover our basest, darkest impulses. Ruby Cooper is her most morally complex character yet. Utterly compelling. (Tammy Cohen)
An utterly gripping story about how one incident reverberates across time, damaging and destroying lives. I read it as if in a fever (Shari Lapena)
Utterly compelling and brilliantly imagined … all the way to the last dark twist. (Anthony Horowitz)
Addictive and awe-inspiring, from the first page to the last. (Diane Jeffrey)

This is a great psychological thriller. No ridiculous twist and turns, but a real look at the disturbing behaviour of multiple inviduals.

Believable

Although this book held my interest, I doubt it would have done if not for the excellent readers. Nowhere near as good as Strange Sally Diamond.

Intriguing

It was my favourite book of the year to listen to. I was hooked and didnt want it to end!

Such great characters

Engrossing, powerful, disturbing… beautifully produced and read. As good as Strange Sally Diamond? No. Shorter and simpler. I was waiting for that one last Liz Nugent twist to make me question everything… but the ending was kind of unsatisfying.

Well written, wonderful narration

Something went wrong. Please try again in a few minutes.
The story was great - perfect level of complicated. Liz Nugent writes fantastic believably twisted characters and page turning plots. I didn't like this as much as her other books, and it was severely let down by the main narrator.

Great story
