DI Nikki Galena is a police detective with nothing left to lose. She's seen a girl die in her arms, and her daughter will never leave the hospital again. She's got tough on the criminals she believes did this to her. Too tough and now she's been given one final warning: make it work with her new sergeant, DS Joseph Easter, or she's out. Her partner, DS Joseph Easter, is the handsome squeaky-clean new member of the team. But his nickname "Holy Joe" belies his former life as a soldier. He has an estranged daughter who blames him for everything that went wrong with their family. Their adversary is a ruthless man who holds DI Galena responsible for his terrible disfigurement. The town is being terrorised by gangs of violent thugs, all wearing identical hideous masks. Then a talented young female student goes missing on the marsh and Nikki and Joseph find themselves joining forces with a master criminal in their efforts to save her. They need to look behind the masks, but when they do, they find something more sinister and deadly than they ever expected...
