She appears, lithe and tanned, by the swimming pool one afternoon. Severine - the girl next door. It was supposed to be a final celebration for six British graduates, the perfect French getaway, until she arrived. Severine's beauty captivates each of them in turn. Under the heat of a summer sky, simmering tensions begin to boil over - years of jealousy and longing rising dangerously to the surface.

And then Severine disappears.

As police suspicion mounts against the friends, Kate becomes desperate to resolve her own shifting understanding of that time. But as the layers of deception reveal themselves, Kate must ask herself - does she really want to know what happened to the French girl?
