Voted the world's most beautiful woman, 23-year-old Mira Roskova is admired, envied and desired. With a world-famous footballer for a boyfriend, plus top modelling and endorsement deals, Mira's meteoric rise to fame comes with what her millions of Facebook and Instagram followers imagine to be a perfect life. 

But celebrity extracts its pound of flesh. Threatened and harassed online, stalked by besotted fans, beaten up by a man who claims to love her, Mira is assailed on all sides. Home isn't safe, friends can't be trusted, freedoms melt away. Where does the image end and the real person begin? 

As the threats multiply, the biggest danger is overlooked. In Broadmoor, Britain's most notorious psychiatric hospital, one man has long been obsessed with this most perfect beauty. His crimes are so awful that a judge ruled they must never be revealed to the public. But his plans to possess Mira are well advanced, and he has the charm and the cunning to make them work.
