Sirens introduces Aidan Waits, a disgraced young detective living in a sprawling northern city.
After he’s caught stealing drugs from evidence, Waits is blackmailed into an undercover operation which sends him from the upper echelons of the super-rich to the low-life squalor of the drug scene.
He spends his nights tailing The Franchise, a sophisticated drugs gang operating out of Manchester’s booming bar culture, impressed by their charismatic leader, Zain Carver.
But when James Rossiter, a powerful member of parliament, discovers that his teenage daughter has run away to join The Franchise – everything changes. Isabelle Rossiter has a history of mental illness and has already survived one suicide attempt.
She joins the dangerous world of the sirens, the young women, each compromised in their own way, who go from bar-to-bar collecting drug money for The Franchise. He meets Catherine, a con woman who moves from personality to personality, and Sarah Jane, Zain Carver’s lover.
Each lives in the shadow of Joanna Greenlaw, Carver’s first partner, a woman who agreed to testify against him but vanished without a trace.
As Franchise members begin to die, and a toxic strain of their designer drug hits the market, it becomes clear that someone doesn’t want Joanna Greenlaw to be forgotten.
His loyalties divided between the police, The Franchise, the sirens and himself, Waits forgets about saving his reputation and tries desperately to save his own life.
