Lilly Valentine, tough talking lawyer and single mother, never makes things easy for herself and her latest case is about to become her biggest challenge yet.

Several years ago, Lilly successfully represented a terrified teenager, Kelsey Brand, accused of the brutal murder of her own mother. Now, ten years later, Kelsey has contacted Lilly again, this time to help her find her missing friend, Gem, last seen working in a strip club in the red light district in Luton.

And when another girl disappears from the same area, the evidence begins to point to a grooming gang targeting young and vulnerable teenage girls. Then Gem's mutilated body is discovered in a desolate country lane and Lilly realises that she must do everything she can to find the still-missing girl before tragedy strikes once more.

But is Lilly a match for the gang of men involved who will do anything, including murder, to get what they want?

As a lawyer in London's Peckham, Helen Black had a loyal following of teenagers needing legal advice and bus fares. Now in Luton, she works mostly with children in care as well as bringing up her own twins.
