Schoolgirl missing / Sue Fortin.

"When fourteen-year-old Poppy vanishes on a family boating trip, suspicion soon turns close to home - to the two people who should do everything to keep her safe, her parents, Kit and Neve. Can they really be responsible for their little girl's disappearance? Neve loves Poppy like her own daughter, but the truth is, she isn't. And her very existence means Neve will never have a precious child to call her own. But would Neve harm her step-daughter simply to get her own way? In times like this Neve has always turned to her sister Megan to help. Megan will know what to do... Kit would do anything to keep his family safe and happy. But his refusal to have another child has been causing a strain on his marriage. And he's worried Neve's mental state is growing increasingly unstable. But would he harm his own daughter just to prove he is in control? As the frantic search for Poppy grows, Kit and Neve's marriage is close to breaking point. And only one person can get what they want."--Publisher's description.
