Lizzie and Alice are the best of friends, as close as can be. Until the day when they’re out playing by the train tracks and a childish spat triggers Lizzie’s epilepsy. When she comes to, she finds an unimaginable horror: Alice has been killed. Lizzie is devastated, and as she tries to cope with her grief, she is shocked to find herself alienated from Alice’s friends and relatives, who are convinced Lizzie and “the dare” somehow had a role in her friend’s death. Years later, Lizzie has tried to move on. She’s engaged to a wonderful man and is starting a new life in London. But someone from her past isn’t willing to forgive and forget. And they’ll do anything to pry answers from her. Even if Lizzie doesn’t know them herself.
