Slave Girls, a new series by bestselling author Louise Allen, reveals a shocking modern-day scandal of County Lines - the single most dangerous form of systematic child abuse prevalent today.

This is the second installment in the brand new series.

Hanna - The Shrinking Girl - has always struggled to fit in. The eldest of five kids, her homelife is complicated and poor, and her single mum, Eva, can barely keep their heads above water.

Bullied at school for her obvious signs of poverty, she is happy and relieved when a cool girl makes a move to be her new friend. But this friendship carries a terrible cost. She is thrown into a dark world of drugs, gangs, sex and a controlling 'boyfriend'.

Repeatedly raped and addicted to drugs herself, a desperate Hanna starts to self-harm and develops an eating disorder.

Totally controlled by a gang that uses her as a commodity, is there any way she can be pulled from their grip and reunited with her family?
