As warring paramilitaries lay down their arms and inch towards a historic peace agreement, Belfast remains a tinderbox of secrets, betrayals, and hidden agendas.

At the heart of this epic tale are young lovers, Ruby and Tom. Ruby is an intelligent and ambitious twenty-something running her father's logistics business. She is smart, determined, and fiercely independent, but Ruby is leading a dangerous double life. She is the secret mastermind behind the Irish Liberation Army - a new radical paramilitary group intent on dismantling the peace process and igniting a new rebellion.

By her side is a former paramilitary commander, and a trusted family friend and nun, with her own hidden past. Together, they build an underground network, recruiting young idealists from university, forging alliances with black market weapons dealers, and trading with Europe's most ruthless criminal organizations.

Tom, is a thoughtful and determined journalist and searching for his first big story. Unaware of Ruby's true identity, he finds himself drawn into a world of deceit and conspiracy. As he pieces together the fragments of her shocking plot, he realizes that the woman he loves may be the key player in a coming storm of violence.

As Good Friday approaches, a catastrophic event shakes the city, launching a desperate hunt for Ruby and her narcissistic brother. The only person who can stop her is Tilly Carson, the youngest Chief Inspector in the Police Force. With time running out and the fragile peace at risk of collapse, Tilly must decipher the web of Ruby's operations, working alongside Tom, to bring her down before she carries out one final, devastating act.
