A tale inspired by the 1984 Brighton Hotel bombing assassination attempt on the lives of Margaret Thatcher and her cabinet is told from the perspectives of an IRA bomb maker, a former star athlete-turned-hotel manager, and the manager's teenage daughter.

In September 1984, a bomb was planted at the Grand Hotel in the seaside town of Brighton, England, set to explode in twenty-four days when the British prime minister and her entire cabinet would be staying there. Weaving together fact and fiction, the story switches among the perspectives of Dan, a young IRA explosives expert; Moose, a former star athlete gone to seed, who is now the deputy hotel manager; and Freya, his teenage daughter, trying to decide what comes after high school. Over the course of a mere four weeks, as the prime minister s arrival draws closer, each of their lives will be transformed forever.
