"The sins of the past will not stay buried. But who are the innocent and who are the guilty?" Kay Kelly has always envied pretty, privileged Violet-May Duff, but the two young girls come from very different worlds. Suddenly befriended by Violet-May, Kay finds herself welcomed into the grand Duff house, where, charmed by Violet-May's sister, the ethereal Rosemary-June, and intrigued by Mrs Duff, a woman with a past, she falls helplessly in love with Violet-May's brother Robbie. It all seems too good to be true. And it is. One mild September afternoon the three young girls take Violet-May's baby brother for a walk in his pram. What happens on Bone Bridge that day will change all their lives forever. Now in her thirties, Kay's path crosses once more with the Duff family and it doesn't take her long to realise that something is very wrong. With the life of a child clearly threatened, Kay is forced to accept that what happened all those years ago on Bone Bridge has come back to haunt her. Now, not only must she resurrect painful memories, but the time has come to finally face up to terrible truths, even if it means putting her own life in danger.
