Vex is used to people being afraid of her special power, the ability to persuade others to do what she wants.

But when she arrives at a new school, Tiebold Academy, it is packed with people who have the same special power as her, and who might even like her.

There is her roommate Ronnie, a coolheaded high achiever; and Ronnie's friend Taye, who is recovering from a brain injury. There is witty, lordly Hannu, whose father happens to be a billionaire. And then there's Ari: troubled, blessed, honourable, terrifying Ari.

Vex is enchanted by her new friends when, five weeks into term one, they are kidnapped.

They find themselves chained in the basement of an abandoned factory, trying to figure out how to escape, all the while tormented by questions like: Why were they taken? Why do the kidnappers seem to hate Vex, and at the same time want to recruit her?

Can Vex and her friends save themselves? And if they do, will they ever feel safe again? What kind of reckoning will they face afterwards? And will Vex again feel responsible for all the bad things that happened?
