'I used to be someone. Someone named Jenna Fox.' Jenna wakes from a coma after a horrific accident to find her life a blank page and her own identity a mystery. Her parents think her recovery is a miracle, but what really happened to Jenna Fox? A gripping thriller set in a future that may be closer than we think.

'Why can I remember the details of the French Revolution but I can't remember if I ever had a best friend?'

When Jenna wakes following her accident, her recovery is slow. One day she can't walk; the next she can. One day her right eyelid droops; the next it doesn't.

But at what cost has her recovery come? What are her parents hiding from her? And why does her grandmother, Lily, hate her so?

When the memories do come, they're more than anyone bargained for, and as Jenna struggles to work out who she is, and what exactly makes us who we are, one thing becomes very clear: Jenna Fox is no ordinary teenage girl.

Who is Jenna Fox?

'I read this book in less than one day - it's a real page-turner! I found Jenna's story compelling, and every character is unique down to the last detail.Nine and a half out of ten.' Lucienne, 18
