Scarlett is dancing in the school talent show tomorrow. Nana, who Scarlett lives with since Mum died, reckons Scarlett will be on Strictly at this rate. Except Scarlett doesn't make it home from school. She's abducted by a man she never imagined she'd see again. A man on the police's most wanted list. Her dad. Ron has made a living as a house and pet sitter since quitting his career on the front line in the fire service. He's currently looking after a place deep in the Derbyshire Peaks. The solitude suits him. And managing animals is so much simpler than coping with other people. Dylan's a 'cuckoo', dealing drugs on the county line, moving from nest to nest, picking out people who daren't say no. Keeping his head down, one step ahead of the law. So far. But now everything's falling apart. DS Laura O'Neil is running on empty after nights dealing with her teething toddler. But Laura is driving the hunt for Scarlett and knows that every minute counts. Any delay, any mistake might cost Scarlett her life. A devastating prospect. PC Ahmed Ali discovers a seriously injured man in a drug den and chases his suspected attacker across the hills. Ahmed is determined to bring him to justice. But fate has other plans in store. A race against time, played out in the brooding wilderness, the limestone gorges and gritstone edges of the Peak District.
