The Guardian Chloe Roberts is on top of the world at Morton Academy. She’s a shoo-in for Head Girl and the lead spot in the school’s secret society: Jewel and Bone. But then her best friend, Nikhita Patel, betrays her, and life comes crashing down.

Things take a darker turn when Chloe stumbles upon the Book of Crime and Punishment – a record of every misdeed committed by Morton students and the fitting penalty. And it’s not long before entries in the book start to match up with murders of Jewel and Bone members. Anyone could be a suspect.

Can Chloe get to the bottom of this twisted game before she’s next on the killer’s hit list . . .
