Synopsis

One child, two mothers and a past that won't let them go. A second brilliantly twisty thriller novel by Sunday Times bestselling author of The Woman on the Ledge.

'Fresh, original, utterly intriguing and so, so clever' ANDREA MARA, bestselling author of No One Saw A Thing

'A clever, compelling rollercoaster ride of a book, never letting up until its final resolution' JENNIE GODFREY, Sunday Times bestselling author of The List of Suspicious Things

'Ruth Mancini has done it again. Smart, twisty and propulsive' HARRIET TYCE, bestselling author of Blood Orange

-------

All Lauren wants is a new life in Spain. She’s suffered an unimaginable loss, but at last she has found a home in the pretty seaside town of Mantilla de Mar. Everyone deserves a new start, and Lauren needs to put her past firmly behind her.

Hope has everything: an interesting career as a therapist, an attractive husband, a dream home in the countryside - and, finally, the baby she always longed for. Sam. Her beautiful boy.

But Sam has gone missing.

So when the police tell her that a woman has been found in Spain with a child matching Sam’s description, Hope thinks that her nightmare might be coming to an end.

But Lauren is insisting Sam is her baby. She even has his passport and birth certificate to prove it.

So what really happened to Baby Sam? And who still has secrets to hide?

One child. Two mothers. And a past that won’t let them go.
