In this near-future YA dystopian political thriller, a medical breakthrough solves the problem of endless old age: now, if a person thinks they have had enough of living, their 'Switch' goes and they instantly die.

15-year-old Margaretta lives in fear of her Switch. Since her mum died at the hands of the Switch four years ago, she has been living alone with her violent father and survived only by shutting out all feelings. Margaretta's emotional armour starts to crack when she meets Sky, a charismatic homeless boy. They run away to the Blue Cat nightclub, where Margaretta discovers the exhilaration of freedom, music, and an intensifying attraction.

Soon, they find themselves drawn into a murky world of political corruption led by the Blue Cat's shady clientele. When they discover brutal kidnappings and censorship at the heart of power, they realise countless lives are on the line. With so much at stake, can they make the world listen in time? And can their blossoming relationship survive?
