There are secrets in every marriage . . . and some are more dangerous than others. Sarah and Marco Moretti are the perfect couple. Together they have travelled the globe building high-profile careers as archaeologists. Now, at a dig in Florence, they are on the brink of the discovery of a lifetime. However their marriage is not what it seems.

Blinded by tears, she drives home alone in the dead of night . . . When Sarah wakes up in hospital, she has no memory of the car accident that brought her there - or the 48 hours preceding it. Gone is the knowledge of her husband's infidelity. But gone too is all recollection of finding the precious necklace. And the loss of those two crucial memories will have devastating repercussions… ''''''''Memory can be the difference between love and hate, survival and death, forgiveness and revenge''''''''''''
