A shocking thriller inspired by the true stories of a male prison officer in a women's prison...Prison Officer Jim Dalton works on the male side of HMP Peterborough. It's a dangerous place, fuelled by testosterone-driven violence, but he has the prisoners' respect. When Dalton is transferred to the female side of the prison, his next shift is so easy he can't believe that the officers over there get paid the same wages. He sleeps well for the first time in years.

Billie hasn't had it easy in life, and she has earned the nickname Damage because she has been known to cause some! Ending up in prison might have been inevitable, but Billie hasn't given up on her dreams yet. If there's a way to get out of prison faster, she's going to find it.

When Dalton is assigned to the young offenders' wing, dealing with female prisoners no longer seems so simple, and in Billie he fears he may have met his match. As Billie starts to turn the screw, Dalton faces losing everything...

Taking a break from his bestselling DI Barton series, Ross Greenwood returns with this shocking, page-turning and utterly compelling glimpse behind the bars of a women's prison. From a man who walked the landings himself...
