Girl in Pieces meets One of Us is Lying, told in Sarah Crossan’s inimitable and award-winning verse.

Connie Ryder is taken from her home in the dead of night and sent to Silver Lake Academy – a remote, high-security facility for ‘troubled’ teens. At Silver Lake, the vulnerable and the violent are locked in together under a brutal regime that aims to improve their behaviour. But when Connie learns she’s been given the bed of a missing girl named Belle, she is drawn deep into a chilling web of secrets and lies… A sensational, immersive and hugely propulsive ‘missing girl’ thriller, set against the backdrop of America’s controversial Troubled Teen industry.
