How well do you know those closest to you?
Jessica McDonald appears to have it all: a successful London banking career, a happy marriage, and good friends.
Then a terrorist bombing rocks London in the wake of the Brexit referendum.
She narrowly escapes injury and tends to others wounded at the scene, too shocked to process what has happened. Lacking support from her husband in the aftermath, she turns to her new work colleague Will Johnston for comfort, setting her personal and professional lives on a collision course with unforeseen and explosive consequences.
Jessica barely has time to recover before another tragedy hits: her beloved father suddenly dies of a heart attack in Edinburgh, and she rushes to her mother's side to comfort her.
Waiting for Jessica in her father's personal effects are instructions in code and the key to a safety deposit box. As she follows the clues her father left behind, Jessica uncovers secrets that will upend the foundations of her life-and put her in grave danger.
Forced from her home and job, Jessica flees to the Scottish coast where she tries to piece together a terrifying conspiracy that has personal and global implications.
Can she stop events that could topple the political establishment of the country? Or will terror succeed?
