The dare / Lesley Kara.

"As a child, it was just a game. As an adult, it was a living nightmare... When teenage friends Lizzie and Alice decide to head off for a walk in the countryside, they are blissfully unaware that this will be their final day together - and that only Lizzie will come back alive. Lizzie has no memory of what happened in the moments before Alice died, she only knows that it must have been a tragic accident. But as she tries to cope with her grief, she is shocked to find herself alienated from Alice's friends and relatives. They are convinced she somehow had a part to play in her friend's death. Twelve years later, unpacking boxes in the new home she shares with her fiance, Lizzie is horrified to find long-buried memories suddenly surfacing. Is the trauma of the accident finally catching up with her, or could someone be trying to threaten her new-found happiness? Twelve years is a long time to wait, when you're planning the perfect revenge . . ."--Publisher.
