Thea wakes from a coma, having forgotten much of the recent past. As well as learning to walk again, she studies the list of ‘facts’ she keeps on her phone, hoping something will unlock her memory. Her top three facts are: I was in Italy I was with the people I love the most I fell down a ravine and I’m lucky to be alive But as Thea gets hazy glimpses of the lead-up to her fall, the facts stop adding up. Trapped at home in the middle of the Irish countryside, dependent on those who were on holiday with her – her fiancé, her brother, her sister-in-law and her best friend – terrifying questions surface: Was I pushed? Why are they lying? Who can I trust? As memories come tumbling back, Thea realises she is in race against time to figure things out – and that her life hangs in the balance.
