Brought to you by Penguin.

*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.
