'This sharply observed novel manages to be at once an intricate puzzle and an involving race against time'
*The Sunday Times*

I loved No One Saw a Thing by Andrea Mara - which saw me deciding I knew what was happening every 5 minutes and realising I was wrong 5 minutes later. So clever. Tense, twisty, turny.
*Jennie Godfrey*

'As soon as I started reading this, I had no choice but to continue reading until the last page. I DEVOURED it. Such a tense, thrilling ride of a novel that played into my darkest fears and captured the emotions of panicked parents so evocatively.'
*Fiona Cummins*

'I dare, nay defy, you to try and put this thriller down!'
